You can go to the toronto humane society website and post on the lost and found page. It comes up on google search a lot. Also, try takign the cat in to the local vet to check for a microchip. If there is a collar, there is a high likelihood that there may also be a chip.
Good luck and thank you for takign care of thsi kitty!!
