Assuming you mean BC:
Marina Park Marina rents parking dependant on space. I don't think they have a launch though.
Marina Park Marina
2060 White Birch Road, Sidney, BC V8L 2R2 (250) 656-0454
Van Isle also in Sidney has a launch and parking. They charge for the launch and probably the parking too.
Van Isle Marina Co Ltd
2320 Harbour Road, Sidney, BC V8L 2P6 (250) 656-1138
There is a pay launch at Sidney itself but I can't say what there'd be for parking. Van Isle is close to Marina Park.
Goldstream Boathouse has a launch so there might be some parking there. It's tight so I would guess they would charge for it.
3540 Trans Canada
Victoria, B.C. V9B 6H6
Be forewarned, Goldstream is at the bottom of a pretty steep hill and access is driving North up the Malahat only so a u-turned may be involved and some good pulling power etc. It's a great spot though at the end of Saanich Inlet.
