Thanks for the suggestions everyone. Fortunately I didn't need to use any of them.
I had my car fully loaded ready for my trip before I realized my car won't start. Went out to grab some stuff to bring back in to make my car less prone to a break-in; thought about giving it a try and it for some reason worked this time.
It was already dark, so my mom suggested waiting until daylight to come, but I was worried it might not start again then, so I made it to Calgary!
So my suggestion for everyone reading this thread, is keep trying every hour or so until it goes. That's what I did.
