You picking it up today in snowstorm? Same thing happened to me last year.
Pretty sure it will come with all season tires.
They will tell you re-schedule your delivery if you don't feel comfortable driving in the snow. And they will make you sign a waver to say you accept to be driving in Quebec with non winter tires and that they are not liable if any thing happens.
It's BS if you ask me someone needs to take them to court really. I tried for a week to get them to swap rims with my winters that I had previously purchased before ever having the car and they refused.
