I take it that you've never listened to any Quebecois. I can understand actual French people. I can understand African francophones. I can't make out but a few words spoken by French Canadians. When AvE talks to his daughter I get "unintelligible ma petite jolie. unintelligible unintelligible unintelligible unintelligible".
That's just an accent problem, just like we discussed within the UK. To alleviate the accent barrier, one needs to judge his abilities at French in writing !
I dare to believe I my written English is about decent, given all the crap I see coming out of native English speakers in Youtube comment sections or random forums. Yet if we were to try and have face to face discussion you and me, it would probably be painful for you to bear with my disgusting pronunciation, and painful for me not to understand half of what you say, well maybe I don't know, because maybe you have an accent I have never heard before or you speak too fast or you don't articulate well enough or god knows what might get in the way of a successful communication...
To this day I still don't understand when I watch American TV series, why there are some people / characters I understand perfectly the first time, without any effort, and others I only get 50% of the words and can't fill the blanks to make up a plausible story. I spent only 3 years in the UK so I guess if I moved up there for 10 more years I might eventually get better... but I will never know.
One of the reasons I subscribed to EEVBlog YT channel in 2013 IIRC, was become somehow, even though he was Australian, I could understand him perfectly well without any effort, even though he speaks non stop, like he doesn't need to breathe.
Shahriar / Signal Path is the same. speaks at the speed of light, yet somehow it comes easy to me. Others, I don't get - at - all...
But as for Quebec people yes I have listened to them...there are a few artists from Quebec who sing in France. Like Robert Charlebois or Céline Dion or Garou or "Coeur de Pirate" . They speak perfect French, no trouble at all understanding them
As for AVE I don't know who he is so can't say ! Will have a look on YT...
