Yeah, there are surely aspects of the immigration program(s) to criticize, but the racism aspect has been either totally unchanged or decreased over time, from my observation. Though, maybe that's unsurprising considering: "Vancouver is one of the most ethnically and linguistically diverse cities in Canada: 49.3 percent of its residents are not native English speakers, 47.8 percent are native speakers of neither English nor French, and 54.5 percent of residents belong to visible minority groups." - https://en.wikipedia.org/wiki/Vancouver
In a, maybe not worst case, but really bad case, where there is violent conflict between the west and the PRC, how mught that play out in BC? My understanding is that a large portion of that 54.5% are from there? In the US during ww2 many Japanese business and land holdings were nationalized and then auctioned off to local business people. It seems like a work of fiction now, but such things have precedent.
