There's something about Toronto in early October that feels borrowed — the city knows winter is coming and grips autumn tightly. I walked the Distillery District one Thanksgiving weekend: 14°C, maple leaves crackling underfoot, cafés serving pumpkin everything. Winter (December-March) is when Toronto leans into its indoor culture: underground PATH system, hockey arenas, the AGO. Summer (June-August) brings the city outdoors — 25°C, patio culture, festivals on the islands. I find May the most underrated: 15°C, cherry blossoms in High Park, and locals who survived winter emerging with gratitude. Each season has its own Toronto.
