Since BC started out as a British Colonial outpost, people of European descent were at the orchestrated top of the human hierarchy. Chinese and Asians & nonwhites in general were a concern to the White majority of early BC.

Multicultural Canada has less than 1% of the world's population. Yet, so many smaller countries are able to have a higher density and larger population than Canada.
Burnaby in Greater Vancouver is part of Canada's largest urban area on the Pacific_Rim. There are still many people who would like to thwart the scale of growth in Greater_Vancouver. They don't want the region to become as big and dynamic as Montreal, Toronto, Calgary, Seattle, SFBA, Melbourne, Sydney & Brisbane.
A big & dynamic urban region means more Asians and more nonwhite people in general. Unfortunatly, some people are still too uncomfortable with that notion.
