How do you plan for Boxing Day + Black Friday + Canada Day + TIFF peak?
Canadian retail has multiple distinct peak windows, not just one. Boxing Day (Dec 26) is Canada's #1 retail event, bigger than Black Friday for luxury and electronics in Toronto, especially Yorkville and Mink Mile brands. Black Friday (US-aligned, late Nov) bleeds into Cyber Monday. Canada Day (Jul 1) drives apparel and outdoor spikes. Thanksgiving Canada (Oct second Mon), different from US Nov, smaller but real. TIFF (Toronto International Film Festival, Sep) spikes hotel + luxury retail. Caribana (Aug), apparel and beauty. Pride Toronto (Jun), beauty + apparel. We build a war-room: (1) synthetic load test at 40× baseline two weeks before Boxing Day; (2) Redis cluster + Varnish FPC with smart-purge; (3) queue-isolated checkout on its own PHP-FPM pool; (4) Moneris + Stripe tokenisation for repeat buyers; (5) winter-logistics-aware shipping ETAs for Dec, Mar (Canadian winter heavily affects last-mile in Ontario / Quebec).
