London ON feels like “Not the other one. Southwestern Ontario's regional city, with the loosest rental market in fifteen years, a licence your landlord needs before renovating you out, and no commuter train to Toronto at all”, while Seattleis “No income tax but a capital gains one, and a payroll levy visa holders can opt out of”. Climate is a real differentiator: London ON — humid continental in the great lakes snowbelt — warm humid summers, cold grey winters, and roughly 194 cm of snow a year from squalls blowing off lake huron. Seattle — temperate oceanic — grey and drizzly from october to may, then a dry, bright and genuinely excellent summer.
