Guide to Merrickville Locks – Rideau Canal

The Rideau Canal is now closed for navigation for 2022 as of October 10th. Locks will not operate outside these dates, but you can still paddle the canal. The exact opening times for locks are available on the official Rideau Canal website; opening hours vary throughout the season.

There’s not a lot of parking near the canal in Merrickville. If you are planning a canoe or kayak trip you might want to park at Clowes or Kilmarnock and paddle in.
