You guys probably joined the US based Tread Lightly. The Canadian one dyed off because there was not enough interest in people running it and more not enough money to get it off the ground.
They also had lots f other political issues as well as Governments not to interested in the program due to most provinces have some kind of tread lightly program. Alberta is Respect the Land and it is underfunded and is hard to get info on. It is also more set up for hikers and quaders.
