Empress of Ireland

A protected 1914 liner in 40 m of cold, fast-moving St. Lawrence water

The wreck of the Empress of Ireland lies in 40 m of water in the St. Lawrence off Rimouski, a protected liner reached by boat and tied in to one of three private mooring buoys. Cold water, currents of more than 2 knots and visibility under 5 m make it a dive for advanced divers, and the deepest point of the wreck reaches 42.7 m.

Also known as RMS Empress of Ireland.

The dive

The Empress is a boat dive, and the paperwork comes first: every diver registers with the Société des récifs artificiels de l'Estuaire du Québec (RAEQ) before the boat heads to the wreck. Over the site, the boat ties in to one of the three private mooring buoys, which is mandatory. The buoys come out in October, and the water is at its warmest in July, at around 13 °C.

The wreck lies in 40 m of water, and its deepest point reaches 42.7 m. Current over the site can run at more than 2 knots, which makes this a drift dive as much as a wreck dive, and visibility is often under 5 m. Taking or moving any object, or any action that could alter the wreck, is forbidden: the Empress is a classed cultural property of Quebec, so divers look and leave everything where it lies.

Know before you go

  • Currents over the wreck can exceed 2 knots, so the dive is for advanced divers.
  • Visibility is often under 5 m, which makes orientation on the wreck at 40 m harder.
  • The water is cold, reaching only about 13 °C at its July peak, so thermal protection matters on every dive.
