Ontario vs. Texas: Ontario Is Larger by Area

Ontario (1,076,395 km²) is significantly larger than Texas (696,241 km²)—about 1.55 times the size.

Comparative Perspective

Geographic Context

Ontario's vastness includes the Canadian Shield (ancient rock, lakes, forests—~60% of area), Hudson Bay Lowlands (wetlands), and the Great Lakes–St. Lawrence corridor where 90% of population lives. Texas spans Gulf Coastal Plains, Hill Country, Edwards Plateau, High Plains, Basin and Range—more ecological diversity in less space.

Why the Confusion?

Texas's cultural prominence, independent republic history, and "everything's bigger" branding create a perception of maximum size. Ontario's lower profile and concentrated population mask its geographic scale.

Both are subcontinental giants—but Ontario wins on paper.
