I find those quetions hard to answer because only you know what's important to you. The term "simple apartment" isn't very helpful.
Maybe you should look up craigslist Vancouver (possibly Richmond if you want to be close to work) and craigslist Montreal?

I would also have a look at other costs, from cell phone to groceries to hydro etcpp...
Your wage won't buy you weather as well, so if you move to Van there are only two seasons, sun/rain and construction. If you're fine with that, welcome to Van! Don't know nothing about Montreals weather....sorry.
Good luck!
