Eric-- Steveston is a remarkable place. We have not been to the shipyard but the fish market from the sterns of the moored fishing boats is a trip. Steveston apparently has the largest fishing fleet in BC, and the daily fish market is worth the drive up there. You can buy everything from live crabs, shrimp and prawns to fresh salmon, halibut--- the list goes on.
They have a very interesting cannery museum that shows what life was like in the multitude of canneries that dotted the BC coast in the early 1900s.
Not far away is the Britannia Heritage Shipyard (what West's photo is of) which shows what shipbuilding was like along the coast. We've not been to this yet, but here's a photo I snagged off the web. It was taken during a BC Forestry vessel rendezvous in 2011.
I don't know if the cannery museum and shipyard are open in the winter. But I believe the fish market is a year-round deal.
Well worth visiting--- we plan to go up again in the near future.
Here's the website for the shipyard.

PS Answered my own question: the shipyard is open during the winter on weekends, noon to five pm.
