Most immigrants today come from Philippines, China and India. And very few among them are Muslim.

Second, while there are many people who immigrated here from Germany, Italy, Spain, Russia, former Yugoslavia, etc, Canada has not become a fascist or communist country. Even though none of these countries have been  democratic throughout their history (one can argue Russia has never been democratic) they have assimilated quite well here. 

Let's not forget, over 60 million people had to die in Europe before Germany and italy became democracies. Muslim countries haven't had to undergo the same upheaval.
