This postmark was introduced earlier this month so it's still crisp and fresh. Little Current sits on the northeast side of Manitoulin Island in Lake Huron. Although technically a town it was amalgamated with the rest of the township and nearby islands to form the municipality of Northeastern Manitoulin. The only road-access onto Manitoulin island is Highway 6 which passes over the Little Current swing bridge: the bridge on the postmark.
The only other way onto the island by car is via the seasonal ferry M.S. Chi-Cheemaun that sails between Tobermory on the Bruce Peninsula and South Baymouth on the island. It's about a 2 hour crossing.
