How were western and northern European immigrants to Canada treated in Canada in the late 19th/early 20th cenu?

I had it in my notes but I swear I can’t find it now..I remember reading that they were preferred over the southern and eastern European immigrants, but were they treated poorly still? Any source sites I could read would be wondeful!
