Hi Halifaxjoe.  Welcome to OSM.  For your awareness, OSM notes are public information regarding improvements to the map. The OSM community maps what's on the ground.  It is not a place map of historical, planned, or fictional geography.

That having been said, I understand Cubieverse uses OSM data regarding real geographic features.  If you'd like to add features to the park, we'd welcome edits conforming to OSM good practices or notes marking specific features of the park (e.g. "bench here" or "this trail signposted no bicycles") that could be useful to other mappers.

I'm marking this "Resolved" since Cubieverse is off topic, but I'd be happy to help if you post specific geographic information about Halifax.
