I live in southern Burlington. I can take a 2 minute drive to la salle park and catch pike, bass, panfish, as well as trout and salmon in the colder months. The only problem with la salle is it's infested with gobbys and they will gladly eat your bait before any other fish gets to it. Besides from la salle, other places such as bronte harbour, cootes paradise, bayfront, etc. will all have some bigger fish kicking around.
The salmon should also be starting to move in about now, try heading down to the fishermans pier at dawn or dusk, cast spoons as far off as you can, and you may get a 20 to 30 pound salmon.
