Ah, I purposefully left it like that because I didn't want to confuse routers. For example, exiting the Rte. Transcanadienne service road eastbound, heading to Bd. Henri-Bourassa O (north), I didn't want there to be announcements of Bd. Hymus. There are several other such cases at this junction.

There's some discussion going on in this thread, regarding such intersections and how to name internal roadways: https://community.openstreetmap.org/t/name-and-highway-changes-at-dual-carriageway-intersections/131397

I think I would consider these stretches of road to be "intersections"? Anyway, my solution was to leave those "intermittent" roadways with no name. What are your thoughts?
