I expect most Quebecois to speak French as a native language with a heavily French-accented English, but it seems like in Marchessault's case, English may be his native language.
Based on this interview though, it seems like he probably spoke both at home as you can definitely hear the French accent in his voice, while still being comfortable speaking English on what feels like a pretty native level.
The french accent is pretty obvious there to me, even if it's not that tick. If he had been a native english speaker, he would have no accents whatsoever. I have seen a lot of hockey players from Scandinavia that have grown to speak english perfectly with no accents. I remember hearing Mats Sundin speak and I was like wow the guy come off like he grew up in North America. It always depends on the invidual. Some lose it quickly. Or you have someone like Arnold Schwarzenegger that will never lose it. What helps Marchessault is that he played his adult hockey mostly in America and that his wife is english-speaking and all his children speak english. Seems like an english household(which is sad to me).
