Both run on local + English at work, so the edge comes down to your sector. Mississauga: Pharmaceuticals & life sciences, Aviation & aerospace, Corporate headquarters & professional services. Seattle: Cloud computing & software, Aerospace, Retail & consumer.
Mississauga feels like “Canada's biggest office market outside downtown Toronto, wrapped around an airport — same Ontario rules as the city next door, at a smaller discount than anyone expects”, 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: Mississauga — humid continental, moderated slightly by lake ontario — hot humid summers, cold snowy winters, and grey lake-effect cloud from november to february. Seattle — temperate oceanic — grey and drizzly from october to may, then a dry, bright and genuinely excellent summer.
