How this is measured
Surface area is from HydroLAKES (Messager et al. 2016, CC BY 4.0) polygons matched to official names in the Canadian Geographical Names Database. Reservoirs count as lakes; a lake made of connected basins may be counted as one. Figures can differ from official ones by a few percent. The Great Lakes, shared with the United States, are left out.
Data as of October 9, 2026.
