Canada's domestic spy agency concluded that China interfered in the last two elections, an official probe heard on Monday, the firmest evidence so far of suspected Chinese meddling in Canadian politics.

Prime Minister Justin Trudeau's Liberal Party won both the elections, held in 2019 and 2021. Under pressure from opposition legislators unhappy about media reports on China's possible role, Trudeau set up a commission into foreign interference.

The commission was shown a slide on Monday containing an extract of a February 2023 briefing from the Canadian Security Intelligence Service (CSIS).
