European charger Canadian iPhone & IPad

I'm not completely sure because it depends on the prongs on the charger and I don't know what they are in Canada. This article may provide some light on the subject: About the Apple World Travel Adapter Kit - Apple Support

Indeed but what about the prongs? Will the OP need the adapter mentioned above?

If the OP's charging in Europe then no, they won't need an adapter since a European charger would work in European sockets. . If they are charging in Canada with a European charger, then yes, they will need an adapter just to be able to plug it into the Canadian wall socket.

The Chargers can be used with any iPhone for any part of the world.
