Nearly a tie: Canada and China differ by barely 4% in area: about 9,984,670 km² against 9,596,960 km².
Canada sits in North America, China in Asia. On the old Mercator map the latitude gap distorted how large each felt beside the other; at true size the answer is simply 1.04×.
The old map muddied it further: Mercator inflates Canada about 4.1× and China about 1.6×, so on a Mercator-style map this pair appears 2.7× apart instead of the true 1.04×.
China fits 1× into Canada.
