In Quebec, April Fools’ Day is commonly called poisson d’avril—literally, “April fish.” The expression can refer to the day, a prank or the person who falls for it. It is ordinary French, not a special restaurant dish or a uniquely Quebec invention.
What poisson d’avril means
In everyday use, poisson d’avril describes the jokes, hoaxes and harmless tricks played on April 1. When the prank is revealed, someone may announce “Poisson d’avril!” in much the same way an English speaker says “April Fools!”
The phrase can also name the paper fish used in the best-known schoolyard prank. Government of Canada language material uses the expression naturally, which is a useful reminder that this is normal French vocabulary in Canada rather than a Quebec-only invention.
The pronunciation is roughly pwah-SON dah-VREEL. In Quebec French, the words do not need a special local translation.
Why people use a paper fish
One familiar tradition is to secretly tape a paper fish to someone’s back and wait to see how long it takes them to notice. It works because the prank is simple, visual and easy for children to make.
The paper-fish tradition also appears across the broader French-speaking world. Quebec participates in that tradition; it did not uniquely invent it.
Where did the April fish come from?
The honest answer is that the exact origin is uncertain. Several stories circulate, but none deserves to be presented as settled fact.
One popular explanation connects April 1 jokes to sixteenth-century calendar changes. Another points to the end of Lent and fish. Others connect the season with fishing restrictions or impossible errands.
Those theories can be interesting, but they should be treated as hypotheses. The expression and custom have a long history in French, while the single definitive origin story people often repeat online is much harder to prove.
What does “faire courir le poisson d’avril” mean?
Quebec also has the older expression faire courir le poisson d’avril, which refers to sending somebody on a pointless errand or encouraging them to chase a false story.
That idea fits the broader April Fools tradition perfectly: the joke is not always the paper fish itself. Sometimes the “fish” is the person being sent after something that does not exist.
How the tradition appears in Quebec
The paper fish is especially recognizable in schools and families, while newspapers, radio programs, public agencies and brands sometimes publish playful false stories.
The scale can range from a paper fish on a classmate’s back to an elaborate announcement designed to make readers pause for a minute. The joke works best when the subject is believable enough to create surprise but harmless enough to reveal quickly.
The key point is that Quebec has its own living use of the expression inside a much wider francophone custom.
Is poisson d’avril uniquely Quebecois?
No. France, Belgium and other French-speaking communities also use poisson d’avril. Quebec’s role is to keep the expression alive within Quebec French, not to claim an exclusively local tradition.
That distinction matters because cultural explainers often turn a shared French custom into something “only Quebec does.” The more accurate story is still interesting: Quebecers use the same recognizable April fish tradition through their own schools, families, media and everyday French.
How to join in without causing trouble
A good April 1 joke should not imitate an emergency, target a vulnerable person, damage property or spread a rumour that will keep circulating after the reveal.
Paper fish, absurd menu items and gentle family jokes are safer than false health, travel or public-safety announcements. Reveal the prank promptly and be willing to stop if the other person is uncomfortable.
The simple answer
Poisson d’avril literally means “April fish,” but in practical Quebec French it means April Fools’ Day and the jokes played on April 1.
The paper fish is real. The tradition is shared across the francophone world. The exact historical origin is uncertain.
