Hey, thanks for that, DoDo!  One of the things that most immigrants do, sometimes even before they learn our language, is "get a better job or another job, live cheap, stick together as a family..."  Historically true in B.C.  Chinese and Japanese worked jobs that whites didn't want to do. [See TFWs].  When the 1858 gold rush moved up the Fraser, Chinese worked gravel bars supposedly "picked clean"--and prospered.
Some BC 20th century stats:

By 1919, Japanese held 3,267 fishing licenses—nearly half the total number issued that year.  
By 1924, Japanese controlled 39 percent of Fraser Valley berry acreage. 
By 1937, Asians held 91 percent of Vancouver’s greengrocer’s licenses, 53 percent of the cleaners and dyers’ licenses and 29 percent of the tailors’ licenses. 
Chinese had a virtual lock on the domestic work scene, work whites wouldn't lower themselves to do.  

In some cases, it soon meant whites would have to work WITH and often FOR immigrants.  No happiness, there, either!
