Never heard of the term "Jewish Preachers". I don't wear a beard myself, but I mingle with those who do, and I've never heard from them that it creates a problem with law enforcement. Either it doesn't cause them problems, or else what problems it does cause they don't find it worthwhile to mention in casual conversation.
From what I can see, CE is not a big subject here so I wouldn't know much about it. As far as general conditions in Canada for students is concerned, international students will have to pay significantly more, around 4 times as much, as Canadian students. Also, Saskatchewan is a very cold place and the temperatures in winter go as low as -50 there so I wouldn't go there. Some university in Ontario or BC would be a better idea. Other than that, accommodations are easily available and there shouldn't be much problem with that.
