Don't know about B.C., but a few years ago when I was looking at a real fixer upper 46' long I did some checking around. It was going to cost $300 for a hydraulic boat mover to take the boat to an RV/boat storage area around 10 miles out of town that said they'd charge, IIRC it was less than $75 a month. So I would check out rural RV storage places.
I know there is one in Chilliwack because I checked out a Folkes 39 up there. Didn't ask how much it cost to keep it there though.
There was a Cal
39 in some guys yard up in Sultan in the mountains in Washington
some years ago. Maybe a farmer with some unused space would like to make a few bucks.
Dancing Bear a Cal
40 was fixed up on a farm near Port Susan. Then he did a transpac.
