Why Canadian Greenhouses Are Sending Our Vegetables to the U.S. (Part 1)

0:01 A Canadian greenhouse just grew a record harvest in the middle of a blizzard, and somehow there's less homegrown food on your plate than there was 7 years ago.

0:13 I'm Abby Inglewood, and this is The Sanity Project. This is part 1 of a 3-part investigation into Canadian vegetable resilience, what this country can actually grow, and why so little of it stays here. Canada's greenhouse sector is up nearly 38% in 5 years. By every headline number, we're growing more food than ever. And yet the amount that actually stays here, per person, just hit a 7-year low. Some people look at that and point to the Netherlands, a country you could drive across in an afternoon, and ask why we don't just copy them.

0:45 The real answer is buried in a system most Canadians have never heard of, one running alongside factories nobody would call farms. And there's a number about growing food indoors in a Canadian winter that should genuinely alarm you. Let's get into it.

1:00 So picture this, you're on, you know, your last winter grocery run right in the dead of February here in Canada. So hot this time of year, right? You're freezing. Mm-hmm. You walk down the produce aisle shivering a little bit and, and you grab a pack of beautiful bright red tomatoes and you check the label and it says grown in Ontario, which honestly feels like a minor miracle when there's a literal blizzard outside. Exactly. But then you pivot, you pick up a head of lettuce or maybe like a bag of cauliflower, and there's that inevitable sticker imported from California or, you know, imported from Mexico.

1:34 Yeah, it's always there. It is. And looking at those 2 items side by side, you kind of have to wonder, like, if Canada has the advanced agricultural tech to grow pristine tomatoes indoors during a freezing winter, why on earth are we still so heavily dependent on international supply chains for almost everything else? Right. I mean, it is basically the defining paradox of Canadian agriculture today. We possess this immense, you know, world-class technological capacity to grow food in really harsh climates, yet our supermarket shelves are just fundamentally tethered to the Southern Hemisphere.

2:07 Yeah. And the US, obviously, just to keep the country fed. Which is exactly why we're tackling this head-on. So welcome to part 1 of a special 3-part deep dive into Canadian vegetable resilience. Our core mission today is unpacking this massive disconnect between what Canada's ag sector can actually produce and what ultimately ends up on your dinner table. Yeah. And just to give you a sense of where we're heading with this whole series, today is really all about the market maze, right? Production capacity versus domestic availability.

2:33 Right. Then part 2, we're going to crack open the massive winter energy bill that's required to actually keep these Canadian greenhouses warm. And finally, in part 3, we'll get into the long-term policy and institutional changes that we'd actually need to fix this fragmented system. Awesome. And hey, before we really pull on this thread, I just want to drop a quick call to action for you. If you're as fascinated by, you know, the hidden mechanics of how food gets to your plate as we are, head over to thesanity.org to comment, like, and subscribe.

2:57 Yeah, your questions and comments actively shape what we investigate, so definitely get involved. Please do join the ongoing investigation.

Baseline Data: Greenhouse boom and production stats

3:04 Yeah. So, okay, listen, let's start with the baseline data here, because to understand why you're eating imported lettuce, we kind of have to look at what Canada is actually growing. I was digging into the recent economic reports from Farm Credit Canada, the FCC, and our domestic greenhouse sector is just undergoing an absolute boom. It's staggering, really. The growth curve is just, I mean, between 2020 and 2025, greenhouse vegetable production surged by nearly 38%. Wow. 38%. Yeah, we hit 944,000 tons.

3:34 So to put that in perspective, nearly 3 out of every 10 fresh vegetables produced in Canada now originate in a greenhouse. We're talking actual mountains of cucumbers, tomatoes, bell peppers. Okay, but here's the thing. We're investigating a food resilience problem. If you just look at that top-line production number, you'd assume we were living in some, like, golden age of domestic food security. But the latest numbers from Statistics Canada show something incredibly counterintuitive. Oh, for sure.

4:00 Right, like, in 2025, Canada saw a 6.4% jump in field vegetable production, pushing us over 2.5 million tons. So we are objectively producing way more fresh vegetables across the board. Right. However, the domestic availability of fresh vegetables for Canadians, meaning like the actual volume of food that stays in the country for you to buy and eat, that fell to 61.8 kilograms per person. And that 2025 drop, that actually marks the 7th consecutive year of decline in domestic availability per person.

4:29 Wait, okay, I need to challenge the logic of this because the whole core justification for heavily subsidizing the Canadian greenhouse industry with tax dollars is You know, to boost our winter resilience. How is it economically viable or even logically sound that we're growing record amounts of food, but there's literally less of it available for Canadians to eat? I mean, the short answer is the United States

Exports: How the U.S. market drains Canadian produce

4:49 export market. Oh, of course. Yeah. Our ag system doesn't operate in a national vacuum, right? It's deeply integrated into North American supply chains. The FCC data shows that Canadian greenhouse exports to the US surged 44%, hitting $2.3 billion in 2025. So, production simply does not equal domestic availability. Okay, so it's, it's like your neighborhood baker making the best bread in the world but shipping it all to the next town over because they pay double, leaving you to just buy imported bread.

5:19 Exactly, that's a great way to put it. But wait, aren't greenhouses supposed to feed us in the winter? Well, they do, they absolutely do feed Canadians in the winter. But in the summer and early fall, when Canadian field vegetables, you know, the ones grown outdoors in the dirt, are finally ready for harvest, things shift. When that massive volume of cheap field produce hits local grocery stores, domestic buyers naturally want to pay less. Right, because supply is super high. Exactly. But the greenhouse operators, they still have to cover the massive overhead of their high-tech facilities.

5:47 So, the wholesale price the farmer gets, before transport and grocery markups— what economists call the farmgate price— that becomes the friction point. Precisely. The farmgate prices for greenhouse tomatoes and peppers, need to stay relatively high to turn a profit. So when Canadian grocers pivot to buying cheap local field crops, the greenhouse growers pivot to the US export market. Because the US buyers will pay more. Yeah, buyers on long-term contracts down there are willing to pay a premium for consistent, high-quality, pristine greenhouse produce.

6:18 From a business standpoint, it just keeps the sector solvent. But from a national food security standpoint, it exposes a huge flaw in how we measure resilience, You know, we can't just assume that building more greenhouses automatically equals more food on a Canadian plate. Man, that's wild. So, since we know these greenhouses are logically chasing American dollars to survive the summer, it kind of forces us to ask, can we outbuild the export drain?

Dutch Comparison: Why the Netherlands model is tempting

6:40 Like, a lot of people point to the world's most famous agricultural overachiever, the Netherlands, and say, you know, why not just cover the country in glass? Ah, right, the Dutch test. The Dutch test. It is arguably the most common comparison made in Canadian ag policy debates. In fact, it's actually the central focus of a comprehensive white paper by the Sanity Project Research Desk that we're using to anchor today's deep dive. Yeah, and looking at the data from Statistics Netherlands, you can absolutely see why people want to copy them.

7:06 I mean, the Netherlands is geographically tiny. You could drive across the entire country in a few hours. Yet in 2025, they produced an unbelievable 5.91 billion kilograms of vegetables. It's crazy. And 1.86 billion kilograms of that was grown strictly under glass. That means their underglass output alone is more than double Canada's entire greenhouse production. So if they can do it, why can't we? We have millions of acres of available land. Can't we just copy the Dutch model and, like, cover the country in glass?

7:35 Well, that is exactly the premise that the Sanity Project white paper argues is fundamentally flawed. Really? Why? Because the Dutch didn't just build glass houses on empty fields. They engineered an integrated, hyperdense industrial ecosystem. If you look at the research coming out of Wageningen University over there, they detail how these facilities actually operate. It's not just about the building, it's about the circular resources surrounding it. Okay,

Dutch Ecosystem: Circular resources and industrial integration

8:01 what, what does a circular resource look like in practice for a greenhouse? Well, it means capturing waste streams from other industries and feeding them to the plants. So for instance, a Dutch greenhouse might be strategically located right next to a fertilizer plant or some industrial manufacturer, and they literally pipe the waste CO2 emissions from that factory directly into the greenhouse. Wait, really? Just straight in? Straight in. Because plants, of course, breathe CO2. By artificially raising the CO2 levels inside the glasshouse, they supercharge plant respiration and drastically increase the crop yield.

8:32 Plus, they pipe in hot water from industrial cooling towers to heat the greenhouses during winter. Okay, that completely changes the definition of a greenhouse for me. We tend to think of them as these, like, quaint standalone glass barns on the edge of a farm. But what you're describing is closer to a petrochemical refinery. It's like a node in an industrial grid. That is the perfect way to look at it. And they also benefit from having specialized greenhouse construction companies, advanced seed genetics labs, and specialized logistics all sitting within just a few dozen kilometers of each other.

9:02 And crucially, they have a highly concentrated affluent market of hundreds of millions of European consumers right next door. The transportation distances are basically negligible. Which brings us to Canada's structural reality. Our geography is, uh, the exact opposite of the Netherlands. Exactly. Over 72% of Canada's greenhouse production is heavily concentrated in Southern Ontario. So building a highly efficient Dutch-style greenhouse ecosystem in Leamington, Ontario does absolutely nothing to solve fresh food access in Nunavut or Northern Manitoba or rural communities in the Maritimes.

9:35 Right, because you can't exactly pipe waste heat across a continent. Exactly. And trucking fragile produce thousands of kilometers, it degrades the quality and skyrockets the price. Well, let me bring in a reader comment that actually touches directly on this idea of regional expansion. Yeah. A listener was asking if interprovincial trade barriers are the real roadblock here. They pointed to the booming Newfoundland cucumber industry as proof that, you know, if we just remove the red tape, local greenhouses can thrive literally anywhere in Canada.

Geography Reality Check: Why regional expansion myths fail

10:02 Yeah, it's a great audience question because interprovincial trade barriers are admittedly a massive headache for the Canadian economy. However, we do have to fact-check the specific premise here using data from Agriculture and Agri-Food Canada, the Newfoundland cucumber boom is a total myth. Really? The data just doesn't back it up? Not even close. In 2025, Newfoundland and Labrador's entire greenhouse vegetable farmgate value was a mere $178,000. Wow, that's, that's nothing. Yeah, and their greenhouse vegetable exports were literally rounded to zero.

10:31 You cannot dismantle geographic reality with deregulation. Canada's extreme winter climate and our vastly dispersed population mean a one-size-fits-all Dutch rollout is structurally impossible. We can adopt their automation, sure, and their crop genetics, but we cannot copy their geography. Okay, fair enough. But if we can't build massive Dutch greenhouse clusters in every province because of the cold and the sheer distance, what about moving agriculture completely indoors?

Indoor Farming: Vertical farms and urban agriculture

10:57 Like, bringing the farms directly into the urban centers where the people actually live? Ah, so you're shifting the conversation from greenhouses, which obviously still rely heavily on the sun, to indoor vertical farming, which is a completely closed environment. Exactly. And this brings up another highly upvoted social media comment that the Sanity Project white paper specifically investigated. So there was this viral claim circulating that a massive abandoned shopping mall in Montreal had been completely converted into a sprawling indoor vegetable farm.

11:24 Mm-hmm. And I mean, it sounds like the ultimate urban renewal fantasy. It does.

Urban Case Studies: Rooftop greenhouses and Goodleaf

11:28 But the white paper clarifies that this specific claim about an abandoned Montreal mall is unverified. There's just no authoritative record of a dead retail mall being converted into a massive ag facility there. However, rumors like this usually stem from seeds of truth, and Montreal actually is a global leader in urban agriculture. Okay, so what is actually happening on the ground there then, if not the mall? Well, you have companies like Lufa Farms operating highly successful commercial greenhouses on top of industrial rooftops.

11:55 And more to the point of vertical farming, Goodleaf Farms recently completed a massive 96,000-square-foot vertical farm in Saint-Paul, which is just outside Montreal. They're producing over 2 million pounds of leafy greens annually, like micro radish, baby spinach, arugula. Wait, 2 million pounds indoors? How does a system like that even function at that scale without soil? They utilize advanced closed-loop hydroponics. So the plants sit in trays, and nutrient-rich water is continuously recirculated across their roots.

12:24 And because the water is captured, sterilized with UV light, and reused rather than just evaporating into the open air or draining into the dirt, Good Leaf uses 95% less water than a traditional outdoor farm. That's incredible. Yeah, and they provide all the photosynthesis using specialized agricultural LED lights that mimic the specific spectrum of the spring sun. Okay, so if Good Leaf is succeeding wildly at 96,000 square feet, I have to go back to the mall idea. Why not just buy up every dying strip mall and department store in Canada and fill them with hydroponic lettuce?

12:55 Yeah, I mean, you already have the building footprint, the loading docks, the urban location. It sounds like the perfect real estate play, right? It sounds brilliant until you look at the underlying mechanics of what a retail building is actually engineered to handle. A shopping mall was built for people and retail displays. It was decidedly not built to handle the latent heat of vaporization from hundreds of thousands of transpiring plants. Meaning, like, the sheer amount of moisture the plants are sweating into the air?

13:19 Yes, exactly. If you start pumping thousands of gallons of water and introducing 80% humidity into a structure built for an Orange Julius and a food court, you are going to get catastrophic mold, rot, and structural failure within months.

Retrofit Limits: Why malls don’t make easy farms

13:34 Oh wow, I didn't even think about that. Yeah, plus the floors aren't reinforced to hold the massive weight of multi-level water racks and the standard commercial HVAC systems. They would instantly fail trying to exhaust the intense heat generated by thousands of agricultural LEDs running 16 hours a day. Retrofitting a mall with industrial waterproofing, agricultural drainage, and food safety systems is almost always way more expensive than just pouring concrete for a purpose-built facility. Man, that structural reality makes a lot of sense.

14:00 Yeah. But even if you build a perfect custom facility, there is a much larger hidden cost to vertical farming, isn't there? Like the energy bill? Oh, the energy math is the ultimate reality check for indoor agriculture.

Energy Math: Field vs greenhouse vs vertical farms

14:11 And to understand this, we really have to look at some eye-opening data published in the journal NPJ Sustainable Agriculture. They measured the embedded energy required to grow 1 single kilogram of produce across different farming methods. Okay, break the numbers down for us. What's the baseline? So growing crops in an open dirt field takes about 1 megajoule of energy per kilogram. Okay, 1 megajoule, got it. Now if you move that crop into a glass greenhouse, you now have to heat it during the winter and run basic circulation fans.

14:39 The energy requirement jumps to about 27 megajoules per kilogram. Okay, 27, that is a significant jump, but I guess the trade-off is year-round production in a frozen country. So it makes sense. But what happens when you move into a completely windowless vertical plant factory? You are now responsible for providing 100% of the light artificially, plus intense cooling, heating, and dehumidification. The energy requirement jumps to a median of 127 megajoules per kilogram. 127 megajoules. Just to put that in perspective for you listening, 127 megajoules is roughly the equivalent energy of running a standard microwave on high constantly for about 35 straight hours just to grow 2 pounds of food.

15:19 That's insane. It is. And the math gets even more extreme depending on the geography. For insulated container farms operating in the extreme cold of the Canadian Arctic, that number skyrockets to 6,000 megajoules per kilogram just to keep the ambient temperature warm enough for the plants to even survive. 6,000 megajoules. Yeah, that completely shatters the illusion that indoor farming is a magic bullet for every crop. It really does. What this energy data tells us is that vertical farms work beautifully for lightweight, fast-growing crops that don't need massive amounts of light energy to create physical mass.

15:49 You know, leafy greens, microgreens, herbs. But windowless vertical farms are an expensive, energy-guzzling nightmare for heavy fruiting crops like tomatoes, cucumbers, or root vegetables. Because, I mean, growing a leafy green is essentially a sprint, right? It's quick, requires low energy, and you're just growing the leaf. But a tomato is a marathon. The plant has to build a massive infrastructure of vines, flowers, and then pump water and complex sugars into heavy fruit against gravity over the course of months.

16:16 Doing that entirely under artificial light is an astronomical waste of electricity. Exactly. The physics simply do not support growing vine crops in a windowless room. Okay, so we've established that our greenhouses

The Missing Middle: Processing, storage, and supply-chain disconnect

16:27 bleed produce to the U.S. export market to survive the summer. The Dutch model doesn't fit our vast geography. And urban vertical farms are energy hogs that can really only grow specialized lettuce. How does Canada actually solve its reliance on imported vegetables? This is where we have to look at what industry experts call the missing middle, specifically, our processing capacity. The missing middle. Yeah, I found a statistic in the National Food Security Strategy that absolutely floored me regarding this.

16:53 It noted that Canada exports $724 million in fresh tomatoes every year, but we turn around and import $511 million in processed tomato products. Like, we are literally loading our fresh food onto trucks, shipping it to factories in places like Ohio to be crushed into pasta sauce and canned, and then buying it back at a premium. Yep, it is the perfect illustration of a disconnected supply chain. The verdict of this deep dive, the main takeaway

Synthesis: The problem lives in the spreadsheet

17:17 synthesizing all of these sources, is that Canada's core problem is not simply that it cannot grow enough vegetables. The problem is that our production our pricing, our transportation, our grocery procurement, and our domestic availability are completely disconnected from one another. They just don't operate as a coherent national system. So the vulnerability isn't necessarily in the soil or the technology, it's in the spreadsheet. Our supply chain is optimized for the absolute lowest quarterly cost, which just severs the domestic connection the moment the weather changes or border opens.

17:47 If total self-sufficiency is a myth, what are we actually aiming for here? Well, the white paper defines the realistic goal as strategic vegetable resilience. It's not about stubbornly trying to grow 100% of everything. It's about building a layered complementary system. And there are 4 distinct layers to making this work. Okay, let's examine those layers. What is the foundation?

Solution Framework — Layer 1: Outdoor agriculture & storage

18:07 Layer 1 is outdoor agriculture and storage. We need to keep growing heavy, calorically dense crops like potatoes, carrots, and onions in the field where the energy cost remains at that baseline line of 1 megajoule per kilogram. But the Critical Pivot is investing heavily in modern controlled atmosphere cold storage and regional processing hubs. And just to clarify, controlled atmosphere storage isn't just like a giant fridge, right? No, it's highly advanced. They seal the room and scrub the oxygen and ethylene gas out of the air, essentially putting the produce to sleep.

18:36 It means the cabbage or apples harvested in August are still crisp and feeding Canadians in February, instead of rotting in a standard warehouse or being shipped to the U.S. for canning. Right. Okay, layer 2. Layer 2 focuses on our large commercial greenhouses. We absolutely keep expanding these in agricultural hubs like Ontario and BC, focusing on the heavy vine crops— tomatoes, cucumbers, peppers. But to fix the export drain, we need a complete overhaul of grocery procurement. We need Canadian grocery chains to sign year-round volume commitments with domestic growers rather than just ditching them the second Mexican field crops become temporarily cheaper.

19:10 Right. Provide the financial stability so the food actually stays here. Yeah, that makes sense. What is Layer 3? Layer 3 is the strategic use of vertical farms. We locate them near major urban centers, like that Goodleaf facility in Montreal. But we restrict their use specifically to highly perishable leafy greens and herbs. These crops benefit massively from hyperlocal distribution because they wilt quickly, and they don't require the massive light energy needed to fruit. We keep the lettuce out of the diesel trucks crossing the continent.

19:38 And the final layer, Layer 4? Layer 4 is regional and northern production. The federal government recently launched a $100 million local food pathway to build smaller, subsidized agricultural hubs for remote communities. You don't evaluate the economics of a northern container farm against a massive, efficient greenhouse in Ontario. You evaluate it against the staggering reality of air freight. Right, the alternative. Exactly. When it costs $15 just to fly a single wilted head of lettuce into Nunavut, suddenly the high energy cost of a subsidized container farm makes profound economic and social sense.

20:11 It's a completely different economic equation based on geography. That is a massive paradigm shift. You know, a resilient food system doesn't mean building a magical glass dome over the entire country, and it doesn't mean outlawing imports. It means disciplined matching, using the right building, the right energy source, and the right crop for the specific region. Imports are always going to fill the gaps in a northern climate, and that's perfectly fine. But international trade should be a strategic choice, not an absolute necessity for survival.

20:39 That is the exact essence of food resilience. Well, as a reminder, this was only part 1 of our series.

What’s Next: Parts 2 & 3 and closing call to action

20:45 In part 2, we are going to look at the other side of this agricultural coin: the massive winter energy bill required to keep all these high-tech Canadian greenhouses warm when it's 30 below outside. And in part 3, we'll explore the institutional and policy changes needed to actually fix this disconnected procurement system. Before we go, a quick reminder: head over to thesanity.org to comment, like, and subscribe. Your engagement literally drives the research. And I want to leave you with a final thought to mull over the next time you're standing in that produce aisle looking at labels.

21:14 Think about the hidden energy miles embedded in the food on your plate. Is a head of field-grown lettuce, trucked thousands of miles burning diesel all the way from California, actually more or less environmentally friendly than a hyper-local lettuce grown in a high-energy Canadian vertical farm in the dead of winter. Oh wow, it really changes how you look at a simple salad. Follow for more fact checks that cut through the noise. What stays with me is that this problem lives in a spreadsheet, not in the soil.

21:44 Canada has the land, the technology, and the harvest. What it doesn't have yet is a system connecting any of it back to your kitchen. Next time, we dig into the winter energy bill hiding behind every one of those greenhouse tomatoes.
