Ouch. Keep at it, try some new things. Sounds like Hartley Bay is a decent spot so maybe you were just there at a bad time or maybe you were using the wrong techniques. There are plenty of good spots within a few hours of Toronto...spots where you can "limit out" within an hour or two. Spend some more time on the water and you will find them. Sorry I have not been to Nosbonsing so can't comment on that fishery, but right next door is Nipissing and I have not had problems catching fish when I go there.
