In Quebec City, the stadium at Laval University is the one most suitable for a CPL team. It’s called Stade TELUS–Université Laval and it can seat a little less than 13,000 people. It has an artificial turf playing field lined for gridiron football. I have attended many Laval Rouge et Or gridiron football games there. There is enough room to install a 115 yard x 75 yard soccer field without removing the running track, but a soccer field 115 yards long would encroach on the gridiron end zones, which consist of red-coloured turf. Ideally the current turf would have to be replaced.
There’s a nice little stadium at Collège F.X. Garneau, which seats about 2,000 people and has a grandstand on one side. The artificial turf there is lined for gridiron football.
There is also Stade CANAC, in Quebec City’s lower town, where the Québec Capitales professional baseball team plays. It seats a little less than 5,000 people and has an artificial turf playing field. It’s designed for baseball.
