OTTAWA--Canadian Prime Minister Justin Trudeau shook up his cabinet Tuesday after one of his longest-serving and trusted economic ministers said he doesn't plan to run for re-election in a campaign that is widely expected to happen later this year.

Navdeep Bains, the country's industry minister, said he wouldn't seek office again and planned to leave the cabinet immediately. In a video posted on his official Twitter account, Mr. Bains said he wanted to spend more time with his family, adding the past year has been difficult for his young daughters. Mr. Bains, first elected to the Canadian legislature in 2004, did not disclose any future plans in his post-political life.

Mr. Trudeau is scheduled to hold a press conference in Ottawa just after 11 a.m. ET Tuesday. As part of the shuffle, the prime minister moved Francois-Philippe Champagne from the foreign ministry to industry, which is in charge of industrial policy and foreign-investment reviews. Marc Garneau, a former astronaut, is now Canada's foreign minister, after serving as transport minister.

The shakeup to the cabinet comes on the day the Liberal government was to begin a cabinet retreat. In recent days, speculation has mounted in Ottawa that a federal election is in the offing this year. Mr. Trudeau's Liberal Party won re-election in 2019 although with a reduced minority mandate, meaning it requires the support of another party to pass legislation and stay in power.

In a radio interview last week, Mr. Trudeau said a national vote "could well happen" this year, although adding navigating the country through the pandemic and delivering Covid-19 vaccines to regional authorities was the priority.

His government has pledged to spend aggressively over the next three years, to help fortify the recovery from the depths of the pandemic and rebuild the economy with a renewed focus on social policy.

Weekly poll tracking from Ottawa-based Nanos Research indicates the Liberal Party enjoys the support of 40% of voters, versus 27% for the second-place Conservative Party. Under Canada's electoral system, 40% support would likely result in a Liberal majority government.
