Toronto

Epidemiological Brief

Toronto's Santé signal is driven entirely by measles, with no influenza, mpox, or dengue data available from Canadian national surveillance at the city level this cycle. Ontario is estimated to have recorded 28 new measles cases in EW19 (425 cumulative YTD), based on national totals from PAHO Situation Report 3 (944 Canadian cases through EW16) and PHAC historical provincial distribution. These are modelled estimates; the next data update is expected by 26 June 2026. Canada's 2026 measles outbreak is the largest in decades, and Ontario accounts for approximately 45% of the national burden by historical distribution. The normalized measles signal is 20.9/100. The composite Santé score is 20.9 (low). Despite the low composite score, the absolute caseload trajectory is concerning. BMO Field and surrounding venues should enforce two-dose MMR documentation for all event personnel, and health authorities should prepare rapid vaccination clinic capacity adjacent to fan zones. Cross-border traveler measles screening protocols with US border health authorities are advisable given close proximity to the New York region. Sante Index v0 is a watching signal, not a forecast.
