I hope you find your kitty soon. Do you live in a house? If so, you can leave out tuna or salmon on your poarch. Have you contacted Toronto Animal Services or Toronto Humane Society. Put up posters in your area, put up posters in vet hospital, talk to the people on your street. If you leave in an apartment, you could ask your landlord,if it would be ok to set up a trap near the entrance. BUT if you do set a trap, you have to monitior every hour. Again tuna or salmon are the best choices to bait a trap.
