From CBC in British Columbia on 3 April 2026:

B.C. Ferries released details Thursday about a “rare operational incident” involving a vessel sailing in rough weather off the northern B.C. coast, almost a month after the vessel sailed close to a rock shoal – with only about a metre to spare. The Northern Adventure – a vessel that regularly sails between Port Hardy, Prince Rupert and Haida Gwaii – hit bad weather, and deliberately changed course to navigate around the difficult conditions.

According to B.C. Ferries, that’s when the ship – which was carrying 90 passengers and 55 crew – sailed into an area of shallower water near Milbanke Sound, travelling “at its shallowest point over a shoal in approximately nine metres of water.” The vessel, which can carry up to 500 passengers and 87 vehicles, needs a minimum navigational depth of about 10 metres, the company told CBC News in an email.

it’s been 20 years since the fatal crash involving the Queen of the North ferry, which ran aground on a voyage between Port Hardy and Prince Rupert in the early hours of March 22, 2006. Two of the 101 people on board — Gerald Foisey and Shirley Rosette of 100 Mile House — were presumed drowned, and their bodies remain missing two decades later. https://uk.news.yahoo.com/b-c-ferries-details-close-023441265.html

No CalMac ferry has ever run aground with the loss of lives.
