Coast Guard responsibility transferred to Minister of National Defence, with new security mandate added

Oceans Act

Plain-language summary · AI-assisted · not legal advice

Responsibility for coast guard services has been moved from the Minister responsible for oceans to the Minister of National Defence. The coast guard's mandate now explicitly includes security functions, such as security patrols and the collection, analysis, and disclosure of information or intelligence — a new item added to the list of coast guard responsibilities. A new standalone provision allows the Minister of National Defence (or a designated Privy Council member) to collect, analyze, and disclose information or intelligence in carrying out coast guard duties. Separately, the oceans minister's general encouragement mandate has been narrowed by removing the reference to coast guard services, reflecting the transfer. Organizations that interact with the Canadian Coast Guard — including marine operators, port authorities, and those involved in search and rescue or marine pollution response — should be aware that their federal point of contact for coast guard matters has shifted to the Department of National Defence.

Who this affects: marine vessel operators · port and harbour authorities · marine search and rescue organizations · marine pollution response organizations · federal departments relying on coast guard support services
