Yes.  But understand those people have the money to seek care outside of the US-it isn't the welfare group doing so. Canada's patients come here under life threatening conditions because Canada has serious bed shortage and a doctor shortage. 

Perhaps worth noting-Canada also has horrendous medical care cost hikes as well each year, just like us. It will get really fun as more of our unfunded immigrants flow across the border. On that thought, it is good for US taxpayers. Might not be so good for Canada who is stretched thin now with unsustainable costs.
