In a bold display of maritime assertiveness, the Canadian frigate HMCS Charlottetown navigated the Taiwan Strait last week, just days before the anticipated arrival of Chinese Foreign Minister Wang Yi in Ottawa. This transit, occurring despite Beijing’s stern warnings, underscores Canada’s commitment to international navigation rights as it seeks to recalibrate its diplomatic relationship with China amid a backdrop of rising protectionism from the United States.
A Strategic Maritime Passage
The Department of National Defence confirmed that HMCS Charlottetown completed its routine passage through the contentious waters between China and Taiwan on May 22, 2026, with the final leg concluded on May 23. This move was notably executed without the accompaniment of allied naval forces, marking a significant moment in Canada’s naval presence in the region.
Initially, the department refrained from confirming the transit, leading to a delay of three days before responding to inquiries from The Globe and Mail. The timing of this voyage is particularly poignant, coinciding with a pivotal visit from Wang Yi, who is in Canada from late Thursday through Saturday—his first visit in a decade.
Diplomatic Tensions and Expectations
The Canadian warship’s transit comes on the heels of a cautionary statement from Wang Di, China’s ambassador to Canada. In an interview last month, the ambassador warned that further military movements through the Taiwan Strait or visits by Canadian officials to Taiwan could jeopardise the burgeoning partnership between Ottawa and Beijing. This relationship is seen as vital for both nations, particularly in light of Prime Minister Mark Carney’s efforts to secure new export markets and foreign investments to mitigate the economic fallout from U.S. tariffs.
Defence Minister David McGuinty has reiterated Canada’s stance that the Taiwan Strait should be regarded as international waters, in accordance with the United Nations Convention on the Law of the Sea. This convention asserts the right of free passage for vessels navigating straits used for international navigation, a claim that directly contradicts China’s view of the strait as an internal waterway.
Historical Context and Current Implications
Canada’s diplomatic history with Taiwan is complex, having officially severed relations with the island in 1970 under Prime Minister Pierre Trudeau. Despite recognising the People’s Republic of China as the legitimate government, Canada has maintained a policy that does not endorse Beijing’s claims over Taiwan. This nuanced position allows Canada to assert the Taiwan Strait as international waters, a critical aspect of its maritime policy.
The recent transit marks a significant continuation of past Canadian naval operations in the region. From 2018 to the resignation of former Prime Minister Justin Trudeau, Canadian vessels navigated the Taiwan Strait 11 times, often in defiance of Chinese objections. Under Carney’s administration, the HMCS Charlottetown’s recent passage represents only the second instance of such a transit, following a similar journey in September 2025 alongside an Australian destroyer.
Monitoring the Situation
The HMCS Charlottetown’s movements have been closely scrutinised, particularly after a period of silence on marine traffic tracking websites, where it was absent for over a week. This disappearance coincides with a goodwill visit to Da Nang, Vietnam, before re-emerging south of the Korean peninsula. Such maneuvers suggest a deliberate strategy in which Canada is signalling its intent to uphold maritime rights while managing its diplomatic engagement with China.
Vina Nadjibulla, vice-president of research and strategy at the Asia Pacific Foundation of Canada, emphasised the broader implications of Canada’s actions. She noted that decisions made in the South China Sea and East China Sea are being observed by key players, including Beijing, Tokyo, Taipei, and Washington.
