In Toronto Latin Americans are traditionally the most NDP ethnic minority. In the 2001 census the two largest Latin American national groups in the country were Salvadorans, who mostly came in the 1980's fleeing D'Aubuisson, followed by Chileans, who mostly came in the 1970's fleeing Pinochet. They are not, to put it mildly, fans of Reagan.
In Montreal they were presumably Liberal pre-2011 just since that was the only game in town. But notice the bio of
the new MP for Honoré Mercier.
Recently there has been a surge of Mexican immigration, so in the 2006 census Mexico had surpassed both to take top spot, with the largest group by far arriving 2001-2006. I would suspect they probably mostly aren't voting for anyone.
