Awesome ... depending on the direction you prefer to go, there are lots of clubs throwing targets outside of TO.
Do you want to just shoot targets or compete?
There are basically "registered" and "non-registered" targets. The three main ones are trap, skeet and sporting and to shoot registered targets, you join the US based organization and then compete where you want (mainly anywhere in North America) and they keep track of your scores. Registered targets are usually more expensive than non-registered.
There are lots of leagues and shoots in localized areas.
Emily Brown has compiled a list of all the clubs in Ontario throwing trap targets. You can contact Emily through the OPTA website (
