Who We Are
MARCO brings together the Chairs of regional municipalities and Mayors of large, single-tier cities, representing over 10.6 million Ontarians–that’s 75% of the province’s population.
As upper- and single-tier municipalities, MARCO’s members deliver services that touch every stage of people’s lives—like housing-enabling infrastructure, drinking water and sewers, police, public health, homelessness supports and social housing, childcare and long-term care beds—and that underpin Ontarians’ most urgent priorities.
Together, MARCO members work to make life better for their residents by influencing federal and provincial decisions through advocacy, policy, and collaboration.
