Not exactly your area but False Creek in Vancouver, BC has two popular anchorages which are administered by the False Creek Harbour Authority. It's right in the middle of downtown Vancouver. To anchor you need a free permit, and it limits your stay to 14 out of 30 days in the summer and 21 out of 40 in the winter.
These rules were created because the locals in their expensive waterfront condominia were unhappy about "derelict" boats in the harbor. I don't know how accurate that description is, but I have seen a couple of clearly derelict boats anchored there for months or years, and the city doesn't seem to be able to enforce their rules. Personally I'd rather stay on good terms with the Harbour Authority.
