I haven't seen a stop here during my last several trips on Albert, and TransitLive app (link to it accessible here: https://www.regina.ca/transportation-roads-parking/transit/schedules-routes/) doesn't show this as a stop for the routes that the stop POI claimed. (Anecdotally, I used the 2 Argyle Park several times over the last two years and don't remember it stopping here at all.)
Removed it in this changeset:
