If I ever succeed getting the Canadien provinces geometry/features, I'll post the recipe.

For a certain point you can request GetFeatureInfo. If you want features, you have to use WFS. But keep in mind. You get only that from the servers, what they want to publish (i.e attributes of GetFeatureInfo).

Thanks! Francois
