Closer than most people guess: Brazil (8,499,400 km² km²) is only about 16%% larger than Canada (9,872,102 km² km²).
Brazil sits in South America, Canada in North America. On the old Mercator map the latitude gap distorted how large each felt beside the other; at true size the answer is simply 1.2×.
The old map muddied it further: Mercator inflates Brazil about 1× and Canada about 4.1×, so on a Mercator-style map this pair appears 4.6× apart instead of the true 1.2×.
Brazil fits 1× into Canada.
