Hello The Birch Pack, it's great to meet you and welcome to chickensmoothie! You can't "earn" C$ per say, you have to either buy it for real life currency or trade for it - but you can set up art shops or trade your pets with other users to get hold of some. (:
If you need any help though, don't be afraid to ask; people with pink coloured names like me are general helpers, and we're always around if you need a hand! Good luck and hopefully I'll see you around! C:
