Aerial imagery is inconclusive but according to https://ville.saint-lazare.qc.ca/doc/pdf/CarteRecreatifsPublics2013.pdf (thanks Rps333!), the path mapped as https://www.openstreetmap.org/way/445920744 currently on the west side of rue du Bordelais is actually on the east side from around this point to the north. Local survey might help, is there an actual pathway, or just sidewalk, or shoulder?
