I'm from Canada too.
My grey eats lots of raw vegetables, sprouts, fruits, unsalted nuts example almonds, pine nuts, pistachios, walnuts, pecans. All organic. I also make my owner mashes and purchase Avian Organic cooked ones too. They are also located in Canada.
In terms of pellets I offer Harrisons High Potency Coarse.
For options where to purchase Pellets in Canada I recommend the following. Great service and great prices. YOu can just email your order in english at ouellet4@hotmail.com if you aren't able to read in french. The owner's name is Jacqueline and she is really wonderful to do business with. I think Most avian vet offices also sell Harrisons too.
