Supply and Demand

Blessed are Ontarians residing near Quebec border. We are now able to rent cars equipped with winter tires.

I have inquired in a Gatineau, QC car rental, across the river from National Capital of Canada, what is the situation with winter tires? Again, there is two news, a good one and a bad one. Yes, such vehicles do exist, but they are very much booked for the season. All the minivans at one particular location are now booked until spring time. Full size cars are still available, but only at certain dates.

One would think free market economy must offer us what we want in abundance. Last few years I was asking for the car or minivan equipped with winter tires in various rental offices in Ottawa, ON with no success. How is that for a supply and demand concept?
