In 2025, Middlesex County marks its 225th anniversary, an incredible milestone that honours more than two centuries of community, growth, and resilience. Since its founding in 1800, the County has evolved while maintaining its strong rural roots, close-knit communities, and deep connection to the land. This anniversary is an opportunity to reflect on the history that shaped us, recognize the people and places that define us, and take pride in the legacy we continue to build together.
History of Middlesex County
Middlesex County has undergone significant transformation over the last 225 years, from Indigenous homelands and early Loyalist settlements to a network of thriving rural and urban municipalities. Originally part of the vast London District established in 1798, the County has seen its borders shift and evolve, especially through annexations by the growing City of London and a major municipal restructuring in the late 1990s and early 2000s. Today, it comprises eight municipalities and supports over 81,000 residents. Its strategic location and access to transportation networks have made it a hub for agriculture, trade, and industry, while its strong infrastructure, including roads, schools, and conservation areas, reflects its commitment to sustainable development and community well-being.
Throughout its history, Middlesex County has been deeply shaped by its people’s resilience, public service, and contributions to national efforts like both World Wars. Key historical landmarks such as the Middlesex County Building — originally a courthouse and jail built in 1829 — remain symbols of civic pride and continuity. Guided by a legacy of community-building, investment in public welfare, and environmental stewardship, the County continues to grow while preserving its rich heritage. Its mission today reflects this balanced vision: to enhance quality of life and sustainability through leadership, strategic planning, and collaboration.

225th Anniversary Celebrations
Tree Planting
On Thursday, June 19, 2025, Warden Brian Ropp planted three trees at the Big Swamp Tract to kick off the 225th anniversary — a spruce sapling, a Kentucky coffeetree, and a white pine.
Tree Giveaway - June 27, 2025
As part of Middlesex County's 225th Anniversary celebrations, the County partnered with the Greenhouse Academy in Thorndale to give away 225 spruce saplings to members of the community, one for each year of our rich history. On June 27, 2025, residents were invited to stop by the Ailsa Craig Library or Parkhill Library branches to pick up a free tree and take part in growing something lasting for generations to come.
The response from the community was incredible. All 225 trees were spoken for. This initiative not only marked an important milestone, but also reflected our shared commitment to sustainability, community pride, and planting the roots of a greener future.
