It's a community mailbox, where mail for multiple addresses can be picked up. That fits the definition of "amenity=letter_box", so I have just changed it to that. Thank you for the suggestion.

Re way #148485129:

You had a fixme note at this location indicating some temporary coastline data.
I have added the complete coastline for the body of seawater known as Wyclees Lagoon, which was rooted off of this way. See changeset #59829988.

I have fixed the problem. That woodland relation is once again intact.

This change worked. The boundaries of these three provincial parks are now visible in OsmAnd.

This is actually the highest point that CanVec gazetted for Gabriola Island. It isn't actually the highest point, though.

Although those tags are also in the relations that bind these areas together, OsmAnd does not show their boundaries correctly, but does properly show the boundaries of other such parks that aren't part of relations. Look at Rosewall Creek Provincial Park for an example.

These changes are meant to make these park boundaries more readily visible in OsmAnd.

Proceeding to fix. Thank you.

I'm thinking the area around the water tower should have the tag "barrier=fence" applied to it.

Well, actually, I was able to quickly fix it, just a short time after bringing it to your attention. Sorry about that.

It looks like you have cut Great Central Lake up into three pieces. Can you fix this, please?

I don't want these roads to be tagged as residential or anything above that. They are not for public use, and should not be described as such.
