OK, with the Falkens and the WRs, if I am not mistaken, you are talking about a summer tire, and a winter tire. You will give up the ability to steer, stop and brake if you use a summer tire in the winter, and using a winter tire in the summer is a detriment to your handling, stopping, et al, but also to your tire wear, as winter tires us a much softer rubber compound.
If yu can find a way to get summer tires for summer, and winter tires for winter, you will be much happier. And you won't need your next set of tires as soon.
If that's too hard to swing, a decent all season is OK, but is still a compromise. In Ottawa, there is no way that I would risk it, but you would have fewer problems in your neck of the woods.
