01 — What to know

The brief.

Crysler Park Marina is the South Dundas anchor — full-service, run by the St. Lawrence Parks Commission, and tied to the Upper Canada Village park product.

The marina's transient slips, fuel, and boat launch make it the practical entry point for visiting boats. The Iroquois Lock at Iroquois is the only Canadian Seaway lock in the South Dundas section and primarily regulates upper-pool water levels above the Moses-Saunders Power Dam; pleasure craft transit on the published St.

Lawrence Seaway navigation-season schedule and transit fees apply, set by The St. Lawrence Seaway Management Corporation.

Best season is the Seaway navigation season, roughly mid-May through October. The upper Seaway pools through South Dundas are flat, regulated water — calmer than open Lake Ontario — but Seaway shipping traffic shares the same channel.
