Siscoe officially files for re-election as St. Catharines Mayor

The mayor of Niagara Region’s largest lower-tier municipality, Mat Siscoe, officially filed his papers to run for re-election late last week. 

Siscoe was first elected as mayor in 2022 and is seeking a second term. He released a statement outlining what Siscoe believes has been accomplished over the past four years and what the campaign might look like in the weeks and months ahead. 

“At the start of my first term we laid out an ambitious agenda with the goal of establishing a strong foundation for the future of our community,” said Siscoe. “Collectively, we met those goals. Our community has faced adversity, overcome significant challenges, and celebrated many successes in four short years.”

“As we look ahead to the future, I have a vision that will build upon the foundation to create an even stronger community where we can all thrive – together,” added Siscoe. “Over the next three months I will have more to share about my vision and my plan for our city. For the moment, I want to thank you all for the opportunity and privilege to have served as your Mayor, and I look forward to continuing our work together to build a strong and thriving community that we all call home.” 

Before becoming mayor, Siscoe was a teacher at the St. Paul Catholic High School. Siscoe was first elected to public office in 2010 as a city councillor and served three terms. He also filled a vacant seat on Niagara Regional Council for a period of time. 

Siscoe ran for the Progressive Conservative Party provincially back in 2014 but lost to incumbent Liberal MPP Jim Bradley, who would later go on to serve as Regional Chair. 

Siscoe, along with Niagara Falls Mayor Jim Diodati and Welland Mayor Frank Campion, endorsed Ontario Premier Doug Ford for re-election back in 2025. 

When Siscoe was elected mayor back in 2022, he won nearly 69 per cent of the vote. Thus far, Siscoe has earned a reputation of keeping property tax increases down.

At the regional level, Siscoe is currently the Chair of the Niagara Transit Commission and is also a member of the corporate services committee, planning and economic development committee, public health and social services committee, public works committee, budget review committee of the whole, and Niagara Regional Housing Board.

Should Siscoe win re-election as mayor, his experience at Regional Council will be significantly different than during his first term. The Ford government recently passed legislation to shrink Niagara Regional Council, eliminating all elected regional councillor positions. Instead, Regional Council will be made up of Niagara Region’s local mayors, as well as a provincially appointed chair, with mayors receiving a weighted vote based on their lower-tier municipality’s population. The mayor of St. Catharines will have the most impactful vote, given the city’s population size. 

Also running for mayor of St. Catharines are Anthony A. Adeoye, Jimmy Jackson, and Ann-Marie Zammit.
