Oh whoops. Well Toronto is the largest city in Canada, and I believe the 3rd largest in North-America.
Not to be totally random, but as of the most recent census data from the US, Canada, and Mexico, Toronto is the 4th largest city behind Mexico City, New York, and Los Angeles. Granted my source is Wikipedia which includes Central America and the Caribbean as part of North America. Toronto is third between the US and Canada, and Montréal would be sixth. Couldn't resist since I'm taking an urban US politics class this semester and see lots of population data.
Bring on the 24th!
