Spruce Nubble Farms in Maine has them from 500 up up up and away! It really depends on the "breed" of GTP.
Look em up on google.... and shipping is 200. 100 for CITIES and 100 for the shipping. It could be more since you are in Calgary but yeah! Look around!
I'm getting one soon, and it will probably be around 800-900 total Canadian dollars... Good luck!
