CCGS Sir Wilfred Grenfell[note 1] is a Canadian Coast Guard vessel based in Victoria, British Columbia.

The supply vessel has capacity for 879.70 m3 (193,510 imp gal) of diesel fuel, giving the ship a range of 11,000 nautical miles (20,000 km) at 11 knots (20 km/h).

[1] Named for a medical missionary to Labrador, the ship entered Coast Guard service in December 1987, replacing CCGS Grenfell.

Sir Wilfred Grenfell was dispatched to aid Capitaine Torres but by the time the ship had arrived, the merchant had sunk and the crew of 18 were lost due to the poor visibility and high seas during the storm.

[8] In 1993, the Sea Shepherd Conservation Society's vessel Cleveland Amory was chased and apprehended by Sir Wilfred Grenfell and CCGS Cape Roger with Royal Canadian Mounted Police detachments aboard for harassing the Cuban fishing trawler Rio Los Casas on the Grand Banks.

[9] In June 1994, Canadian law changed with the Coastal Fisheries Protection Act that gave Canada the right to manage fish stocks within 200 nautical miles (370 km) of the coast.

Sir Wilfred Grenfell successfully executed the move, and the net was later recovered and demonstrated the illegality of the European's vessel fishing tactics.

[10] On 1 January 1994, a signal indicating a ship, the 81,000 GRT Marika, had sunk in the mid-Atlantic was received by the Coast Guard at Halifax, Nova Scotia.

The Coast Guard and Canadian Forces were mobilized and Sir Wilfred Grenfell was dispatched, and assumed control of the search upon arrival.
