Hi, 

Sorry for delay replying here.

I can agree that highway=path is a little problematic.

One issue is that there isn't a widely-accepted definition of what a path actually is, and there's a lot of discussion in the community right now. Some examples:
- https://community.openstreetmap.org/t/pathway-for-ways-not-used-by-or-intended-for-cars/118981
- https://community.openstreetmap.org/t/documenting-the-problems-with-highway-path/119103
- https://community.openstreetmap.org/t/history-of-proposals-to-fix-highway-path-ambiguity-and-a-wayforward/118877
- https://community.openstreetmap.org/t/documenting-solution-proposals-for-highway-path/119773

So for this case I think the problem we're seeing is that this is what we could call "a wide pathway" but there's no agreement on whether it's a highway=path

In Canadian terms, its built form is similar to a multi-use path or a shared-use path. Some of these are indeed wide enough for a car to drive on. There's no general agreement on how to tag those. Some that are primarily used by cyclists get by with highway=cycleway and possibly foot=yes, for example the trail over the Humber bridge https://www.openstreetmap.org/way/33398082 or the Humber River Trail https://www.openstreetmap.org/way/873348032

In this case I don't think it should be a cycleway, because cyclists aren't really the primary or usually not even half of the users (partly due to hills, partly due to frequent crowding with pedestrians).

But what I don't like here is a highway=service tag. I read that tag as a car-focused tag, or at least car-first. To me, highway=service are laneways leading to garages, or in High Park, the service roadway leading to the greenhouses https://www.openstreetmap.org/way/14345156 - it's not really where you'd walk as recreation.

What do you think about tagging this path as highway=footway? It would align with its primary use. We could tag width=* to indicate the size. Alternatively, for "more substantial" foot paths, there's highway=pedestrian - and that's used on Spring Road and Deer Pen Road within High Park - so it could be an option here too.

For the path along the bottom of the pond, along The Queensway, I would actually suggest highway=cycleway? It's similar in practice to the ravine/river trails or the Humber bridge.

Cheers,
