Guide to Clowes Lock – Rideau Canal

Lock Station Dates & Hours: the system usually opens around the Victoria Day weekend at the end of May and closes around the Canadian Thanksgiving in early October. The last day of operation for 2021 is 11th October. Lock hours vary with season and can be viewed on the official Rideau Canal site.

The entrance to Clowes Lock is east of Merrickville on Highway 2. Keep a good lookout, it is signposted, but looks a bit like you are driving into someone’s yard. Parking is just as you enter the property although it seems to be OK to drive down to the lock to drop off your kit.
