The City of St. Catharines is marking a major milestone in 2026.
St. Catharines Mayor Mat Siscoe officially launched the City’s 150th anniversary celebrations with a ceremonial flag raising at City Hall on Monday, marking the beginning of the milestone year under the theme “Our Common Ground”. While its roots trace back much earlier, St. Catharines was officially incorporated as a City on May 1, 1876.
“This anniversary is about more than marking a date on the calendar,” said Mayor Siscoe. “It’s about recognizing what we share as a community — our histories, our neighbourhoods, and the people who have helped build St. Catharines over the last 150 years.”
The event, featuring a flag bearing a special 150th anniversary logo, brought together community leaders and representatives from all levels of government, including remarks from St. Catharines MP Chris Bittle, St. Catharines MPP Jennie Stevens, and Chair of Niagara Region Bob Gale, alongside members of St. Catharines City Council and the City’s senior leadership team.
The theme “Our Common Ground” was highlighted throughout the ceremony, emphasizing the shared history, values, and experiences that have shaped St. Catharines. A portion of the vision – which can be read in its entirety on the City’s website – states: “The land beneath our feet has been one constant that has endured – well before St. Catharines attained City status. It bore the footsteps of the first Indigenous peoples, offered shelter to freedom seekers on the Underground Railroad, and gave rise to the waterways, vineyards, orchards, and gardens that nourish us today.”
The St. Catharines 150 logo mark carries on with that theme, inspired by land parcels and community patchwork: individual plots that sit side-by-side to shape a bigger whole. Each parcel represents a piece of St. Catharines - past and present residents, cultures, industries, and neighbourhoods coming together as one city.
The flag raising marks the first of several commemorative events and initiatives planned throughout the year, all designed to reflect the City’s past, present, and future.
Highlights include:
Additional events and opportunities for public participation will be announced throughout the year as the anniversary celebrations continue.
