You missed the one where we turned away Jews in the 30s because we thought they would change our Country.  And many complained about Irish being so rebellious (with their own terrorists)  to be good citizens and the Italian mafia culture being too corrupt for Canadian law and order.  Name a diaspora and I'll name you the prejudice.

I personally have worked with and friended dozens of Muslims here, and not one has ever indicated  they wanted to change our institutions to suit them.
