I saw a convoy of about 30 cars on the highway back in October. I looked it up and found nothing. Then I see a Reddit post in /r/vexillollogy with the same flag and no useful answers.
It’s so weird that people bought like 100 of these flags and there is no info on them at all!
I flipped the picture to make the flag the right way.
The Quebec plate I missed before. That and the trucker convoy sticker along with the green color suggest some sort of Quebecoise right winger.
