Q: Thankkkk You!
A: depends on what bands you like theres a couple rock shirt stores along yonge, one south of bloor and another north of dundas, both on the east side. black market, diagonal from whatever the much/city building is called now, has lots of stuff - especially in smaller sizes - and in kensington there's a store called exile that has similar shirts. if you like punk, goth, industrial and other stuff try out the shop across the street, and another one on the south hand side before by the kfc (don't know the names off hand, sorry)
