Ordered winter tires and wheels from Canadian Tire tonight. Their website is flaky, kept kicking me off at various points in the process. I think it took three tries to actually check out and get a confirmation email.
Anyway, I’m a firm believer in winter tires.
I’m also a believer in having them mounted on an additional set of wheels.
Yes, there’s the initial expense, but if you keep tires mounted, the cost to swap them is much less than having to remount tires on wheels every season.
If you take your car in for servicing, the shop will often swap your tires for free as part of regular maintenance, as long as they are already mounted on wheels. They have to take your wheels off anyway to check brakes, etc.
Or if you have a spare hour or two, you can swap them yourself.
Just make sure, ahem, your nuts are nice and tight. 
And check them again a week or two after the swap. . .
