Whistler is a bit different microclimate than Vancouver, but they're predicting a very wet fall and pretty sure winter in the city. In the Whis village it's below freezing way more often and consequently snows way more, but the precip isn't always the same. I find Whistler gets a lot of little dustings and regular fresh than the north shore mountains that seem to mostly get big dumps of wet Cascadia pow when the temp in the city is down around 6° or so and the rain is hammering.
After last year being one of the driest winters on record, and it still being an at least okay year snow-wise in the mountains I wouldn't be surprised if this year had lots, assuming the predictions are any indication. I've heard some mixed things about the snow predictions though, just laying out what I know about the climate here to maybe make a guess.
