Kreid,
I live in Toronto. You'll be closer to Ottawa I believe which is 4 hours away (400km away).
If that's correct then there's very limited trout or salmon opportunities for you. However there's lots of warm water lake and river fishing opportunities.
Ontario is so vast it's hard to explain to someone from across the pond. We literally have hundreds of thousands of lakes.
Typically though you'll find bass (smallmounth and largemouth, pike/muskie, panfish (sunfish, crappie, etc), walleye and coarse fish (e.g. carp). Deeper lakes have lake trout, whitefish and brook trout.
Your best bet is to research the specific area and talk to locals.
The best bet for an Ontario fly fishing board would be hipwader.ca. However info may be limited as most focus on river fishing. Alternatively try either this
Ontario OUT OF DOORS Community - Powered by vBulletin
or this
Ontario Fishing Community Home -> General Discussion
these are the most heavily used general fishing forums for Ontario and probably you'll get help there.
Good luck.
