Calgary Open Data indicates that there is an amenity=toilet facility here (the existing building in OSM?). It is hard to see the building from aerial imagery, and the building outlines don't match. Does such a toilet exist? Is it the existing building in OSM or a different building?

"Cafe C'est si bon" is approx here. I was a patron last week, but didn't have time to check if it was on the map. A local may have to survey to see if it is a "new" waypoint for OpenStreetMap, or if an existing business waypoint has closed and changed names.
