My fave B&B is on Dundonald Street in downtown Toronto, but I have no idea of space available. I took the liberty of forwarding the proprietors your e-mail. They may reply one way or the other.

Alternatively there's Palmerston House which is hardly as close to the center of things as is the Bay/Bloor area, but very elegant if also quite pricey. I think they're close to C$200/night now. I do have their phone (416) 920-7842, and fax (416)960-9529 if you wish to pursue. I will be in Toronto the end of June, very much looking forward to the vacation. Regards, Daniel
