Where to buy bird food in the GTA?

Just moved to Aurora and looking for good bird supply stores. Where do you all buy your pellets, treats, and fresh food? Any stores that specialize in bird nutrition?

Just wanted to come back and say the advice in this thread WORKED. My Eclectus finally stopped chewing furniture during out-of-cage time after I tried stuffing paper towel rolls with treats for foraging.

I've done a ton of research on this because my Indian Ringneck had the same issue. Here's what I learned: the most common cause is a subtle environmental change you might not even notice. What worked for us was covering the cage partially at night for 12 hours of uninterrupted sleep. I also started adding more variety in perch textures and sizes and noticed improvement within a week. It's a process but it gets better.
