jjcanoe is correct, you can catch specs pretty much threw out all of southern Ontario, the tough job remains finding your own personal honey hole and of course not over fishing the resident population, it only take a few people to over take their limit and honey hole has now become a HOLE. My advise would be to invest in a topography map (only cost you a few bucks) and fish alot of the feeder creeks off any of the major water systems (Credit, Humber, Grand) You'll be surprised at how a small trickle of water can hold some nice size specs.
Good luck
