On 9 March 2025 Mark Carney won the Liberal Party leadership with 85.9 percent of the vote, succeeding Justin Trudeau as leader and becoming prime minister-designate. Neighbouring Brookfield non-disclosure is stored separately.
Context
Trudeau had announced resignation on 6 January. Neighbouring 14 March oath is a child. He had never held elected office.
Brookfield file the same day is stored separately. Oath 14 March is the child.
The Prime Minister of Canada heads the federal ministry, advises the Governor General, and sets Cabinet weather. He does not write a Bank of Canada overnight rate by himself once he has left that building, a US IEEPA tariff, a provincial pipeline certificate, or a Brookfield board minute after a blind trust. A housing target is not a unique completed unit count. A climate-envoy speech is not a later pipeline MOU.
Why it matters
The path is democratic resilience: a completed certified party leadership contest.

What the sources establish
Liberal Party of Canada carries the official instrument or communique. Associated Press records the same dated act independently.
Established: 9 March 2025 85.9 percent result, independently reported.
Not established: a unique later Commons seat from that Sunday — he still lacked one — or a unique later GDP coefficient.
He ran. Trudeau remained PM until 14 March.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Carney wins the Liberal leadership with 85.9 percent, not a later speech about Carney wins the Liberal leadership with 85.9 percent.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to Party members voted. He ran. Trudeau remained PM until 14 March. That limit is the alternative to treating office-holding as authorship of every later series.
