I could only find out information from the province of Alberta. You would need to sit the exam in Canada, although it looks like there are some home-study materials that you could get sent out to you.
For more info on Alberta, check out:

Also Lakeland College:

Click in the applet on the left side of the screen to access the pesticide applicator training programs. This is valid for Alberta only, but they may have info on B.C. if you contact them.
