Data synthesised from Foodland Ontario (Government of Ontario), Ontario Greenhouse Vegetable Growers, and regional farmers’ market reports. Week boundaries are approximate and shift with weather — southern Ontario (Niagara, Essex County) tends to run 1–2 weeks earlier than the GTA. Climate shifts over the past decade have generally extended growing seasons by 1–3 weeks. Items marked as “regional highlights” are uniquely associated with the Toronto/southern Ontario foodshed and worth seeking out at local markets.
