Bonnie Crombie was elected as a Member of Parliament (MP) in 2008. She represented the area of Mississauga—Streetsville. She won against the person who held the seat before her, Wajid Khan. He had switched from the Liberal Party to the Conservative Party.

After being elected, she worked with Justin Trudeau on a Liberal Party committee. She also became the Liberal Party's critic for Crown corporations. This means she was responsible for watching over government-owned businesses.

In the 2011 federal election, Crombie lost her seat. The Conservative candidate, Brad Butt, won. He received 43.8% of the votes, while Crombie received 36.9%.

Municipal Politics (2011–2024)

On September 19, 2011, Crombie won a special election. She became a city councillor for Ward 5 in Mississauga. She took over from Eve Adams. Crombie won by a small number of votes.

After Hazel McCallion, the long-time mayor of Mississauga, retired, the 2014 mayoral election was very important. Bonnie Crombie and other candidates ran for mayor. Hazel McCallion supported Crombie, which helped her a lot. Crombie won the election with 63.5% of the votes.

Crombie ran for re-election as mayor in 2017 and won again in 2018. She received 77% of the votes. She won her third term as mayor in the 2022 election by a large margin.

As mayor, Crombie wanted to separate Mississauga from the Region of Peel. This is a larger government area that Mississauga is part of. In 2023, the provincial government supported this idea.

During a debate in November 2023, Crombie said she would not run for mayor again in 2026. She planned to finish her three terms as mayor. She also said she would likely run to become a MPP in the 2025 provincial election.

After winning the leadership of the Ontario Liberal Party, Crombie announced her resignation as Mississauga mayor. She stepped down on January 12, 2024. She wanted to focus on leading the Ontario Liberal Party. Carolyn Parrish became the new mayor.

Provincial Politics (2023–Present)

In early 2023, people started talking about Bonnie Crombie running for leader of the Ontario Liberal Party. She was seen at party meetings. On June 14, she officially started her campaign. She took a break from her mayor duties to focus on the campaign.

Crombie was a strong candidate in the Liberal leadership race. She promised to make life more affordable and improve healthcare. She also wanted to build more homes and fight climate change. She described herself as "fiscally responsible" and "socially very progressive." She won the leadership election on December 2, 2023. She resigned as mayor on January 12, 2024.

In January 2024, a provincial seat in Milton became open. Crombie thought about running for that seat. However, she decided not to. Another candidate, Galen Naidoo Harris, ran instead but lost the election.

On March 18, 2024, Crombie announced that she would not put a provincial carbon tax in place if she became premier. This was different from the federal Liberal Party's approach. She said she would not tell the federal government how to do their job.

In August 2024, the Ontario Liberal Party announced speakers for their meeting. They included former leaders from other provinces. This was seen as a way to show the party is different from the federal Liberals.

On September 21, 2024, Crombie and the Ontario Liberal Party showed their new logo. Their new slogan was "More for You."

On December 3, 2024, Crombie again said that the federal carbon tax was "wrong."

Crombie led the Liberals in the 2025 Ontario general election. The party finished in third place. They won enough seats to be an official party again, but not enough to be the main opposition. Crombie also did not win a seat in the Ontario legislature. She came in second in Mississauga East—Cooksville. However, she said she would continue to be the Liberal leader. On March 1, 2025, the party's executive council voted for her to remain leader.
