Trump Tariffed Everything Canada Grows. He Never Touched the Winter Tomato.

Picture an American grocery store in January: a perfect stack of ripe red tomatoes, glossy cucumbers, bell peppers in every color. The honest answer for where that "summer" actually came from is a small Ontario town under more greenhouse glass than almost anywhere else in North America — in a country famous for brutal winters. Canada sends the US more fresh greenhouse tomatoes, peppers, and cucumbers than the US sends back — despite Florida, California, and the entire Sun Belt. It traces back to one farmer, Umberto Mastronardi, who saw Dutch greenhouses in the 1940s and decided to stop fighting Ontario's weather and control it instead. Canadian greenhouse vegetable exports grew from $1.6B (2020) to $2.3B (2025) — up 44% in five years, almost all destined for the US. As a "wholly obtained" agricultural product, greenhouse vegetables are CUSMA-compliant and exempt from Trump's blanket tariffs, the same protected category as canola and potash. Nobody in Washington has ever floated a special tariff on greenhouse peppers — taxing them would mean taxing the produce aisle itself in the dead of winter, when American growers have nothing to offer as a substitute. The honest, surprising twist: Canada has now recorded SEVEN consecutive years of declining fresh vegetable availability for its own domestic market, even as production hits records — because American buyers absorb a growing share of everything these greenhouses produce. Canadians are growing more tomatoes than ever and getting less access to them. And the dependency actually flips in deep winter, when even Canadian greenhouses go dark and Canada imports from Florida and Mexico instead.
