No. The claim that Toronto is larger than Rhode Island is incorrect.
Rhode Island is about 5 times larger than the city of Toronto. Even the Greater Toronto Area (GTA) (~7,125 km² / 2,751 sq mi)—which includes surrounding municipalities—is larger than Rhode Island, but the city itself is not.
This comparison often confuses municipal boundaries with metropolitan regions. Rhode Island is the smallest U.S. state, but still dwarfs most individual cities globally.
