Niagara Municipal Elections Deliver Political Upsets as Three Veteran Mayors Lose to Challengers

NIAGARA REGION, ONTARIO: A dramatic shift in municipal politics has swept across Ontario’s Niagara region after voters removed three longstanding mayors from office, delivering unexpected victories to challengers and raising questions about political complacency, public frustration and the growing demand for accountable local leadership.

The municipal elections held Monday, October 26, produced significant defeats for Niagara Falls Mayor Jim Diodati, Fort Erie Mayor Wayne Redekop and Port Colborne Mayor Bill Steele, all of whom had established substantial political experience and recognition in their communities.

Political observers say the results demonstrate that even deeply established incumbents cannot take electoral support for granted, particularly when challengers organize effective campaigns and connect directly with residents concerned about local issues.

David Siegel, a retired Brock University political science professor and longtime observer of Niagara politics, suggested that overconfidence may have contributed to the defeats.

However, he also emphasized that the successful challengers deserved considerable credit for their organization, determination and ability to mobilize voters.

The election results represent one of the most notable changes in Niagara’s municipal leadership in recent years.

Only five incumbent mayors secured re-election across the region, while several other municipalities were already preparing for new leadership because their sitting mayors chose not to run again.

The mayors of Lincoln, Welland and Thorold, along with Niagara-on-the-Lake Lord Mayor Gary Zalepa, did not seek another term.

Together, these developments have created a substantial turnover in municipal leadership at a time when Niagara’s regional government is also undergoing major structural changes.

One of the most surprising results occurred in Niagara Falls, where longtime Mayor Jim Diodati was defeated by city councillor Lori Lococo.

Diodati had served as mayor for 16 years and was widely regarded as a formidable political figure with extensive experience and strong public recognition.

However, unofficial election results showed Lococo winning 51.45 per cent of the vote, compared with Diodati’s 41.73 per cent, in a five-candidate contest.

The margin represented a decisive victory for Lococo and brought an end to Diodati’s four consecutive terms as mayor.

Lococo initially registered to seek re-election as a city councillor before changing course and challenging the incumbent mayor.

Her campaign ultimately succeeded in persuading enough residents that Niagara Falls needed a different approach to municipal leadership.

Siegel said Lococo benefited from a well-organized campaign supported by volunteers who worked actively to build voter support.

He also questioned whether Diodati’s announcement that another victory would mark his final term may have weakened the motivation of some supporters.

According to Siegel, such statements can create a sense among campaign workers that an established politician is certain to win and therefore does not require the same level of effort.

He argued that successful politicians must campaign with the urgency of candidates who believe they could lose, regardless of their previous electoral record.

Siegel pointed to the political career of the late Jim Bradley, who represented St. Catharines at Queen’s Park for 41 years and later served as Niagara’s regional chair.

Bradley was known for maintaining an energetic approach to campaigning even after decades in public office.

Siegel suggested that the defeated mayors may have underestimated the importance of maintaining that level of electoral engagement.

In Niagara Falls, Lococo’s victory also reflected her reputation among supporters as a councillor willing to question decisions and challenge the majority at city hall.

Residents Caitie Cushman and Gary Wilkins, who supported her campaign, said they valued her preparation, independence and willingness to scrutinize municipal proposals.

Cushman described Lococo as a politician who carefully reviews information and asks detailed questions rather than simply agreeing with other council members.

Wilkins similarly praised her preparation during council meetings, saying she regularly arrived with extensive documentation and demonstrated a strong understanding of the issues being discussed.

Supporters also highlighted Lococo’s opposition to substantial property tax increases.

Affordability has become a major concern for households across Ontario, and municipal taxes can have a direct impact on homeowners already dealing with higher housing and living expenses.

Wilkins suggested that Lococo’s record of challenging large tax increases resonated with Niagara Falls residents who are struggling financially.

Her victory indicates that voters were willing to support a candidate who presented herself as a more critical and independent voice on council.

The election also demonstrated the importance of local issues in shaping political outcomes, even when incumbent politicians have extensive experience and name recognition.

Another major upset occurred in Fort Erie, where Mayor Wayne Redekop was defeated by Tom Insinna, a regional councillor and former RCMP officer.

Redekop had served as mayor for nine years beginning in the 1990s before returning to the position in 2014.

His lengthy political career made him one of the region’s most experienced municipal leaders.

Nevertheless, unofficial results showed Insinna winning by a double-digit margin.

The result suggests that a substantial portion of Fort Erie voters were prepared to embrace new leadership despite Redekop’s longstanding involvement in municipal government.

Insinna’s experience as a regional councillor and former police officer provided him with a background in public service that may have strengthened his appeal to voters seeking change.

In Port Colborne, incumbent Mayor Bill Steele also suffered a significant defeat, losing to former longtime city councillor Bea Kenny.

Kenny returned to municipal politics after an eight-year absence during which she cared for her late husband while he battled cancer.

Her return proved successful despite Steele’s established political profile and the longstanding presence of the Steele family name in Port Colborne politics.

Siegel noted that defeating a candidate associated with such a familiar political name was a considerable achievement.

Kenny attributed her victory to direct engagement with residents, particularly through door-to-door campaigning.

She said personal conversations with voters helped her earn their confidence.

Her success reinforced the importance of traditional grassroots campaigning in municipal elections, where direct contact between candidates and residents can play a decisive role.

While digital advertising and social media have become increasingly prominent in political campaigns, local elections often remain heavily influenced by personal relationships, neighbourhood concerns and candidates’ willingness to listen.

The defeats of Diodati, Redekop and Steele have prompted discussion about whether established municipal leaders had become too comfortable in their positions.

However, the results cannot be explained by overconfidence alone.

The successful challengers brought their own experience, campaign strategies and political messages to the contests.

Lococo had a record as a sitting councillor, Insinna had regional government experience, and Kenny had previously served for decades in municipal office.

Their victories were therefore not simply the result of public dissatisfaction with incumbents but also reflected the availability of credible alternatives.

The election comes at a particularly important moment for Niagara because the Ontario government is preparing major changes to the region’s governing structure.

In April, Ontario Municipal Affairs Minister Rob Flack announced plans to reduce the size of Niagara Regional Council.

Under the proposed restructuring, the council would shrink from its current 32 members to 12 municipal mayors and a provincially appointed regional chair.

The changes would eliminate the existing broader representation model and place greater responsibility on mayors to make regional decisions.

This restructuring adds significance to the municipal election results because many of the newly elected mayors will soon be expected to participate in decisions affecting the entire Niagara region.

Regional government oversees important services and responsibilities that account for a substantial share of residents’ property tax bills.

With several inexperienced mayors entering office, the balance of influence within regional council could shift considerably.

Siegel believes the election results may strengthen the position of St. Catharines Mayor Mat Siscoe, who secured a substantial victory and won a second term.

St. Catharines is the largest municipality in the Niagara region, giving its mayor an important role in regional affairs.

The province’s proposed weighted voting system would also provide greater voting influence to municipalities with larger populations.

Under such an arrangement, Siscoe could hold significantly more voting power than mayors representing smaller communities.

Siegel suggested that Siscoe’s experience and position as mayor of the region’s largest city could make him one of the most influential figures on the restructured council.

With approximately half of the incoming mayors having limited experience at the regional level, established leaders may play a greater role in guiding discussions and decisions.

The restructuring also creates an intriguing possibility for some of the politicians who lost or left their mayoral positions.

Siegel suggested that Diodati could potentially be considered for the provincially appointed regional chair position.

The former Niagara Falls mayor’s extensive municipal experience could make him a candidate for the role, particularly given the provincial government’s interest in appointing someone familiar with regional governance.

Siegel also identified retiring Welland Mayor Frank Campion as another possible contender.

Diodati’s previous support for Premier Doug Ford could be politically relevant, although no appointment has been confirmed.

The possibility of a regional leadership role means Diodati’s defeat may not necessarily mark the end of his involvement in Niagara politics.

Attempts to obtain his response following the election were unsuccessful.

Beyond the individual candidates, the election has highlighted the importance of voter participation in municipal democracy.

Siegel pointed out that several races across Niagara were decided by extremely narrow margins, with some contests separated by only 40 or 50 votes.

Such results demonstrate how a relatively small number of ballots can determine the leadership of an entire municipality.

Municipal elections frequently attract lower voter turnout than provincial or federal contests, despite the direct impact local governments have on daily life.

Decisions about property taxes, roads, infrastructure, housing, development and public services are made by municipal councils.

The close margins in several Niagara races provide a reminder that individual votes can influence those decisions.

Siegel urged eligible voters who did not participate to recognize that their ballots could have made a difference.

The 2026 municipal election has also illustrated that political longevity does not guarantee continued public support.

Incumbents may benefit from established networks, administrative experience and name recognition, but those advantages can be overcome by determined challengers who respond effectively to changing public priorities.

For residents facing affordability pressures, higher municipal expenses and concerns about government accountability, candidates who promise closer scrutiny of spending and more responsive leadership may have particular appeal.

The victories of Lococo, Insinna and Kenny suggest that voters in several Niagara communities were ready to reassess longstanding political relationships.

Their success will now be measured not only by their election campaigns but also by their ability to deliver effective municipal governance.

New mayors will face the challenge of fulfilling campaign commitments while managing municipal budgets, infrastructure requirements and regional responsibilities.

They will also need to establish working relationships with fellow councillors, municipal administrators and provincial officials.

The transition could become more complicated as Niagara adjusts to the planned restructuring of regional government.

For St. Catharines and other municipalities whose incumbent mayors secured re-election, the changes may create opportunities to exercise greater regional influence.

For communities that elected new leaders, the coming months will test whether political change produces the improvements voters expect.

The dramatic results have already sent a clear message across Niagara’s political landscape.

Experience and public recognition remain valuable, but they are not substitutes for sustained voter engagement, effective campaigning and attention to residents’ concerns.

As Niagara prepares for a new chapter in municipal governance, the defeats of three prominent mayors stand as a reminder that no elected position is guaranteed and that even the most established political figures remain accountable to the voters they serve.
