Designed by Robert Allen Ltd it was built by Halifax Shipyards, when it was owned by the Dominion Steel + Coal Co, for the British Columbia forestry giant MacMillan-Bloedel. When it was launched October 26, 1965, at a cost of $1.25mn, it was the first tug built by the yard. Delivered to MacBlo's shipping arm Kingcome Navigation Ltd and named Haida Brave it went into service towing barges from Port Alberni and Powell River, BC to San Francisco and Long Beach, CA. The 350 ft long barges could carry 6500 tons of newsprint, and the trip could be up to 1200 n.mi., at the stately speed of 8 knots.
For this work the 566 grt tug was fitted with two 8 cylinder Werkspoor engines delivering 3470 bhp to twin screws.
The tug worked consistently through 1978 for Kingcome, then Reliance Towing Co when it was sold to Rivtow Straits Ltd, also of Vancouver and renamed Commodore Straits. It then expanded its duties towing log and cargo barges until it was laid up in 1990.

In 2003 it was acquired by an affiliate of the Upper Lakes Group Inc of Toronto and given a thorough refit at Allied Shipbuilders Ltd in North Vancouver. It sailed light tug via the Panama Canal and arrived in its new home port of Trois-Rivières, QC December 3, 2003.
Upper Lakes set up Distribution Grands Lacs / St-Laurent Inc., and used inland river type covered barges, shuttling grain from the Lakes through the Seaway to its elevator in Trois-Rivières. The tug was not particularly well suited to pusher work, but spent some years on an off moving the barges.
By 2008 Upper Lakes established Marinelink Inc as a heavy lift operator to work on the St.Lawrence. They found an old heavy lift ship in the southern US and sent Commodore Straits to pick it up. It towed the Barge Laviolette south for sale to scrappers and returned with the ship Revival ex John Henry.
Joined by the tug Océan Golf off Pointe-au-Pic they stopped in Trois-Rivières.
Then in September 2008 Commodore Straits was joined by the tug Radium Yellowknife and towed the ship to Port Weller Dry Dock where the superstructure was removed and it was reduced to a barge. Renamed Marinelink Explorer it retained its heavy lift derricks. The tug's ownership was also transferred to Mareinlink Inc and it received a small elevated wheelhouse for visibility over the barge.
The barge did find occasional work, but was mostly idle, and the tug as well. Other tugs were moving the grain barges more efficiently.
In 2011 Upper Lakes laid up the tug and barge and offered them for sale. At the same time Upper Lakes sold off its cargo ship fleet, bunkering tankers and other shipping interests. Finally in 2013 Distribution Grands Lacs / St-Laurent was allowed to go into bankruptcy.
In late 2013 CAI Logistics of Moncton, NB acquired the tug and barge. CAI was the company of Chaulk Air and other freight forwarding companies with business in Labrador and the far north, but had not been shipowners. The tug was renamed Chaulk Determination and the barge Chaulk Lifter.
The years of work and layup had taken their toll on the tug's engines and it is understood that a rebuild was started but abandoned. Some work was found for the barge using hired tugs.
The tug is now leaning against its pier in Trois-Rivières, and likely to capsize, having already spilled a large quantity of its 22 tonnes of fuel. A very big mess to clean up. See a picture and read more (in French) at:
