Same methodology as the U.S. map — population density x drive time to nearest PCI, using the ACC/AHA 90-minute guideline as the threshold. Centroids are population-weighted for major urban regions. In Canada, dense + beyond guideline is not empty. Orange dots = PCI centers. Hover the legend to highlight regions.
In the U.S. bivariate map, the dark red cell — Dense + >90 min — is empty. Zero counties. In Canada it contains 1.1 million people across 4 census divisions in the Quebec City–Trois-Rivières corridor. Combined with 5.5 million in moderate-density regions beyond 90 minutes, nearly 11 million Canadians — 28.7% of the population — live beyond the guideline threshold.
Canada's PCI centers are almost entirely confined to the southern urban corridor. The green on this map hugs a thin strip along the U.S. border. Everything north relies on thrombolytics, transfer, or medevac as the primary STEMI strategy.
