Day trip charter to the Chilliwack River for white sturgeon fishing and/or trout/salmon. Not sure about the seasons for the latter. 

Fraser River on the Big Island has/had magic salmon fishing by all accounts.
Should be plenty of charter boats to pick from out of the city even.
Fished a little with a WW2 uncle of mine across the boarder in the Puget Sounds many moons ago.
Beautiful area.
Water is cold enough that almost everything you catch you can eat.
