I did but my family is québécois and I grew up in northern NB. I remember it being a thing there but not after moving to northern Ontario.

"Poisson d'avril" is synonymous with "April fools" in my experience even in Ontario but without the actual fish part.

Still do. Every year i prépare a few dozen of fishes with double aide tapes ready to stick.i keep some to myself and distrbute thé test to collègue i know will use them. Im in Montréal. There are many of them left over around thé shop from Years ago.

Never heard of it, and we have a pretty large French population here in Manitoba.
