Not Canadian, but the ones from Target Barn work well.
not sure what the brand is but i like the ones that are perforated. They hold up to cold and hot weather. They also seem to stick the best under wet conditions. You can purchase them from mdgardner.com
The Target Barn ones are what we are using now, but they don't seem to be reliable in the kinds of weather in which we shoot. Any significant moisture in the air or low temperatures, and they just don't want to stick.
WYSE pasters?
