Correction

This size comparison is backwards: Lake Ontario is larger than Lake Ladoga by roughly 900–1,100 km², not smaller.

Full reasoning

Authoritative sources put Lake Ontario at about 19,009 km² in surface area, while Lake Ladoga is about 18,135 km² including islands. That means Ladoga does not exceed Ontario by around 1,000 km²; rather, Ontario is larger by about 874 km² on those figures. Even alternate commonly cited Ladoga figures excluding islands are smaller still, which only strengthens the contradiction.

So the sentence reverses the comparison: the larger of the two is Lake Ontario, not Lake Ladoga.
