So, you’re looking at the Canadian political landscape and wondering: just how long has Trudeau been in power? It feels like forever for some, and for others, it’s just a blur of colorful socks and "sunny ways" that turned into "tough days." Honestly, the answer depends on whether you're counting his time as the face of the nation or his total career in the House of Commons.
If we're talking about his time as the 23rd Prime Minister of Canada, Justin Trudeau served for roughly 9 years and 4 months.
He was sworn in on November 4, 2015, and his premiership officially wrapped up on March 14, 2025. He didn't just disappear into the night; he resigned as the leader of the Liberal Party after a decade at the helm, handing the keys to Mark Carney. As of early 2026, he's no longer the guy calling the shots in Ottawa, though his shadow still looms pretty large over the current minority government.
How Long Has Trudeau Been in Power? A Timeline of Three Mandates
To understand the length of his tenure, you have to look at the three distinct chapters of his leadership. It wasn't one long, smooth ride. It was more like three different seasons of a high-stakes drama.
The Majority Era (2015–2019)
Trudeau’s first four years were his most powerful. After the 2015 election, he held a massive majority. Basically, he could pass almost any law he wanted without needing to beg other parties for votes. This is when the "big" things happened—legalizing cannabis, introducing the Canada Child Benefit, and pushing through the federal carbon tax. He was the golden boy of the international stage, appearing on the cover of Rolling Stone while the world watched with a mix of curiosity and envy.
The First Minority (2019–2021)
Things got messy in 2019. The SNC-Lavalin scandal and some old photos surfacing definitely took the shine off. He won the election, but he lost the majority. For the next two years, he was on a shorter leash, needing the NDP or the Bloc Québécois to keep his government alive. This era was defined by the COVID-19 pandemic, which saw him shifting from "progressive leader" to "crisis manager" almost overnight.
The Final Stretch (2021–2025)
In September 2021, Trudeau called a snap election, hoping to regain that lost majority. It didn't work. He ended up with almost the exact same minority situation. He eventually signed a "confidence and supply" agreement with Jagmeet Singh and the NDP to stay in power until 2025.
But by early 2025, the internal pressure became too much. He announced his resignation in January 2025, citing a need for a "reset" for the party. He stayed on until March 14, 2025, when Mark Carney was officially sworn in as the new Prime Minister.
The Misconception About His Total Time in Ottawa
People often confuse his time as Prime Minister with his time in Parliament. If you're asking how long he’s been a part of the federal scene, the number is much higher.
- First Elected: October 2008 (Member of Parliament for Papineau).
- Leader of the Liberal Party: Since April 2013.
- Total time in the House of Commons: Over 16 years.
He spent seven years as an opposition MP before he even got a whiff of the Prime Minister’s Office. That’s a long time to be sitting in those green chairs, listening to other people talk.
Why the Length of His Tenure Matters Right Now
It’s 2026, and Canada is navigating a very different world under Prime Minister Mark Carney. But you can't talk about the current economy without talking about the Trudeau years. Nine years is a long time for any leader. It’s enough time for policies to either bear fruit or rot on the vine.
His supporters point to the Canada Child Benefit, which legitimately slashed child poverty rates across the country. They see the $10-a-day childcare agreements as a legacy that will last for generations. Honestly, for many families, those checks in the mail were a total game-changer.
On the flip side, critics argue that his nine years in power led to a massive housing crisis and a productivity slump that Canada is still struggling to crawl out of. The debt-to-GDP ratio, which he promised to keep low, ballooned—partly because of the pandemic, but partly because the Liberals liked to spend.
What Really Happened at the End?
The transition in 2025 wasn't exactly a peaceful passing of the torch. There was a lot of backbench grumbling. By late 2024, Liberal MPs were openly questioning if Trudeau was the right guy to lead them into the next election. The "Team Canada" approach he used to handle Donald Trump's first term was being tested again by a trade war and retaliatory tariffs.

He stayed in power long enough to see his signature carbon tax become a massive political liability. By the time he stepped down, the polls were brutal. It’s kinda fascinating—the man who started with "sunny ways" ended his tenure in a period of deep economic anxiety and polarized politics.
Actionable Insights for Following Canadian Politics
If you're trying to keep up with what's happening now that the Trudeau era is technically over, keep an eye on these things:
- Monitor the Carney-Trump Dynamic: Much of the current news cycle is focused on how the new PM is handling trade pressures from the U.S., a battle Trudeau started but couldn't finish.
- Check the $10-a-day Childcare Progress: The goal was to have this fully implemented by 2026. Watch for reports on whether waitlists are actually going down or if it's just a subsidized line-up.
- Watch the NDP: They held the balance of power during Trudeau's final years. Now that they've tasted that influence, see how they interact with Carney’s more "technocratic" style.
The question of how long has Trudeau been in power isn't just about a date on a calendar. It's about a decade-long shift in how Canada sees itself. Whether you loved him or couldn't wait for him to leave, nine years as PM is a marathon, not a sprint.
Focus on the policy outcomes that are still affecting your wallet today, especially in housing and carbon pricing. Those are the real markers of his time in office.
