What would immigrants have to do in order for you to be certain they were loyal and committed to Canada?
Adapt to our culture and values and put aside their own. That includes, most visibly, not hiding women under bedsheets and letting them out of the house, even when there are men around not in their families. Recognizing that women don't hide their faces in Canada, nor even their hair, and stop assuming that Canadians are less moral than you are because they don't have your extreme sexual hangups.
Stop hating Jews. That would be good, too.
