Today, Rob Flack, Minister of Municipal Affairs and Housing, announced the following Heads of Council for Durham, Halton, Niagara, Peel, Waterloo and York regions, Muskoka District and Simcoe County:

  • Kevin Ashe, Durham Regional Chair
  • Ann Mulvale, Halton Regional Chair
  • Frank Campion, Niagara Regional Chair
  • Nando Iannicca, Peel Regional Chair
  • Scott Davey, Waterloo Regional Chair
  • Steven Del Duca, York Regional Chair
  • Scott Aitchison, Muskoka District Chair
  • Don McIsaac, Simcoe County Chair

“Ontario stands at an important juncture. As we navigate geopolitical challenges and create the conditions for growth, strong leadership at the regional level is more important than ever,” said Flack. “These appointments reflect our confidence in local leaders who bring a deep understanding of their municipalities and a proven record of performance and public service. As Heads of Council, they will foster collaboration across municipalities, support responsible growth and ensure services are delivered efficiently, so that these communities remain great places to live, work and raise a family.”

Heads of Council are equipped with powers to streamline decision-making, improve efficiency, strengthen alignment with provincial priorities, including housing and infrastructure, and introduce upper-tier budgets.

Parry Sound-Muskoka MPP Graydon Smith congratulated Scott Aitchison on his local appointment.

“I want to extend my sincere congratulations to Scott Aitchison on his appointment as the next District Chair of Muskoka,” said Smith.
“Scott brings a wealth of experience and a proven record of public service to this important role. Having served as a Huntsville Town Councillor, District Councillor, Mayor of Huntsville and Member of Parliament for Parry Sound–Muskoka, Scott knows our communities, understands the issues that matter to local residents and has longstanding relationships across the District.
His extensive municipal experience, combined with his leadership on housing policy at the federal level, makes him exceptionally well qualified to help address the challenges facing Muskoka, particularly housing affordability, infrastructure needs and responsible growth.
I’ve had the pleasure of working alongside Scott for many years and know firsthand his commitment to our region. I am confident he will provide strong, effective leadership that reflects the unique needs of Muskoka’s communities, and I look forward to working closely with him and District Council to advance our shared priorities.
I also want to extend my sincere thanks to outgoing District Chair Jeff Lehman for his service over the past four years. I have appreciated the opportunity to work with Jeff and thank him for his contributions during his time as Chair. I wish him all the best in his future endeavours.
I congratulate Scott once again and wish him every success in his new role.”
Heads of Council bring a range of experience and expertise to their new roles, including municipal governance and administration, infrastructure delivery and finance.
