Depends on where you are. In major cities like Vancouver[1] and Toronto[2], you have over half of the population belonging to "non caucasian". Although this doesn't directly mean all of them are immigrants, subsequent generation tend to carry (or at the very least but influenced) by their parents cultural values, like work ethic. Anecdotally, I'm a second generation Taiwanese living in Vancouver and I consider myself to have the "asian" work ethic.
