I'm guessing that its more popular outside of Quebec than within.
Since its dedicated to the defeat of the French army in Mexico, its a treat for anglos to have a party and annoy the french all at the same time!
Since the Quebec government (and the Pure Laine and La Meute --Wolf Pack ) gets all snotty and "offended" when anyone wants to celebrate the Brit victory over the french at the Plains of Abraham.
Viva la revolucion!
