Someone at Garmin wrote back to me and we have been emailing back and forth. They are looking into why the additional JCV that includes Canada junction views for my Nuvi 2555 was not downloaded with Garmin Express. No timeline on when it will be fixed but the engineers responsible for looking into the matter will probably look at it some time next week. In the meantime the person at Garmin sent me the missing JCV file. I haven't had a chance to install it yet but I looked at its contents in ImgTool and it does contain Canadian photoreal junction views.
