Not likely, though I have not lived in Vancouver full time for some time (about 8 years), I don’t know what the weather is like day to day. It used to be really predictable, but in the last few years, there’s been wild cold snaps. Generally, the lower mainland is pretty sheltered from the weather in the rest of Canada so unlikely to get stuck. Though if there’s a dusting of snow, the rest of the country makes fun of us because most people don’t know how to drive in it.
Someone mentioned the AHL games. Sorry, that’s what I meant when I said Colosseum games. That’s where they host the AHL games. It’s at the Pacific National Exhibition, which is on the east end of Vancouver. Some great tips from the other commenters. I would vouch for not driving across Canada. I’ve done a part of it for work, and though the Rockies are pretty, I wouldn’t do it in mid/late autumn until summer unless you’re comfortable driving in snow, ice and fog.
The autumn foliage will be more October. I love it because I love the cold. If you’re looking to spend a few coins (especially since your currency trumps ours by a lot), the Rocky Mountaineer might be something to look in to.

Why not do a basic food safety course? It could help you find a job (a server, anyone even passing food to customers in a container is considered a food handler like a cashier, even a dishwasher because they handle clean dishes that touch people’s food), and it’ll help you keep you from getting sick.
One of my first jobs between school years was as a busser before I worked a summer in a chocolate factory. From there, you talk to people and get their insights from their previous jobs, and you figure out if it’s something you could stay in longer or if it’s just a job to pay the bills.
