I think you need a refresher course on Canadian history. The Scots cleared from the highlands didn't want to come to Canada. They were evicted. And the Irish driven here by famine didn't want to come either. They too were evicted by the English landlords. They came here and were treated as cheap labour. 

And 2 to 10% misattributed paternity! Not really a scandal. I have no idea where you're going with that as you can't be suggesting indigenous men were busy with the white women. The unknown fathers were much more likely to be neighbours and friends rather than men off the reserve.
