I used the suggestion "Add addresses to all the homes on Barnet Road to help any apps using OSM data to find the correct location" as that is the easiest to implement and works. OSM still has both "Barnet Highway" and "Barnet Road" being used on the same stretch of highway so it should be resolved somehow. It appears Port Moody uses the term "Barnet Highway" and the City of Burnaby uses "Barnet Road" which complicates the matter even more.
