I suspect bigotry is fairly evenly spread---immigrants are just as likely to resent refugees as anyone else. Speaking as "old stock" (200 years in Canada),  I would like you to remember who supported Trudeau in his move to accept immigrants from all over the world without regard to country of origin; and in sponsoring Chilean and  Vietnamese refugees;  who supported public health care; who supported peacekeeping; who, if you look at earlier generations, rolled out the post-Depression social supports we all lean on. And if you look at private sponsors of refugees now, you will find that every stodgy, old-stock church is supporting a family or two (mostly Syrian Muslims) and will continue to support as needed, even when the year is out. You have a fantasy picture of "old stock" that doesn't fit. Canada has a reputation for being liberal because the "old stock" has been progressive for generations.
