After NY 37 and NY 812, the road begins to leave Ogdensburg, and the lands around NY 68 become less developed. NY 68 passes the Ogdensburg International Airport after the intersection with County Route 28A (CR 28A). The highway crosses through Oswegatchie uneventfully, entering the hamlet of Flackville. Much of the region between Ogdensburg and Canton is mostly fields, and NY 68 heads through sparsely populated areas until it reaches Canton. The highway parallels a creek before entering the village of Canton.
