Looking at the FIFA site, the full draw for the qualifying groups takes place on 25th November. The South Americans all play in one big group so they can just get on with it and so that's why they've started their games.
Canada are obviously in the North American group and all 35 countries have entered so they are vying for 3 places (with another one place available through a play off). But until the draw, you won't know what chance the Canadians have. But , usually, the USA, the Mexicans and the likes of Costa Rica or Trinidad/Jamaica are the strongest nations.
