In Ontario for equipment?
My favourite is Bunnyview. Joyce takes her time, helps you figure out what you need, and is easy to deal wit h.
There are couple other suppliers. Like Brian at Grandview Rabbitry. and
SunnyMeadows. up in Barrie. There is supposed to be a fellow on south side of London as well but I don't him at all. :)
For toys?
One could make their own or go searching on-line for items.
Two places on the pet forums are Bunny Bytes and Bunny Approved. Biggest thing is have fun with your bunny and be safe in what you give it. :)
