The geographic distribution and habitat of Patera appressa (Say, 1821) in Canada are described. This is a North American land snail native to the southern Appalachians but it has been known, since 1994, from a cluster of sites in Trenton, City of Quinte West, Ontario, where it is presumably introduced. It may no longer be extant at any of the known Ontario sites.
