Shopping for suits in t.o.

For all the Torontonians out there, where do guys buy your suits from?  I'm in my mid twenties and heading back to school in the fall, so I have a fairly limited budget.  I need to dress up for work sometimes so I have some fairly nice suits (Hugo Boss, JP Tilford, Armani, etc) but I'd like to purchase a few more.  I usually buy my suits from Holt's or Harry Rosen but the steep prices can be a bit much to take for someone in my situation.  Any suggestions would be greatly appreciated.  Cheers.

Thanks for the advice guys.  I have been to both these places in the past.  They seem a little hit and miss but I'll be sure to visit them both again in the near future.  What do you guys think about the quality of Holt's house brand?  What about the quality of JP Tilford and Sameulson suits at Harry Rosen?
