Description: How much of each Great Lake is Canadian? — Open Data Canada, 28-second video.

Splitting each Great Lake along the International Boundary Commission's surveyed line, Canada holds 61% of Lake Huron, 55% of Lake Ontario, about half of Lake Erie, 36% of Lake Superior and none of Lake Michigan — 37% of all five lakes combined. The split is back in the news because President Trump's August 27, 2026 order renamed Lake Ontario “Lake America” inside the United States.
