Canadian Food Forest Plants

Hello,

We are starting a food forest in Dunham Quebec, and I am having a hard time finding these plants:
-Chinese Yams
-Groundnuts
-Hog Peanut
-Sunchoke
-Turkish Rocket
-Sea Kale

Basically, everything Jonathan Bates from Food Forest Farms sells. It is too complicated to import plants from the US, so if anyone has any leads about a Canadian source, please share!
