Is it normal for a Tim Hortons to have very few customers on Victoria Day long weekend in Canada?

I went with my cousin and aunt and uncle and dad to Tim Hortons today after taking a walk around the area, and very few people were seated on the patio. It might have been just us for part of the time we sat and ate and talked. But I saw a bunch of restaurants near by and they were filled to the brim with people, so much, that the seats were over crowded and looked more like punishment congestion then a leisurely and happy meal to celebrate Victoria Day.

One possible reason is that other people assumed Tim Hortons would be packed so avoided visiting. I know there were very few cars in the parking lot when we stopped by to go on our walk to Tim Hortons.

I also remember when I went to the restaurant on Halloween and the restaurant was almost empty. But its possible everybody was in the bar area and I was in the dining area.
