Pickering ON

The Municipal Property Assessment Corporation (MPAC), established in 1998, is composed of a team of experts who understand local communities and assess every property in Ontario. Their work provides the foundation that municipalities use to determine local property tax distribution needed to pay for the services used every day. MPAC is Ontario’s property market expert, responsible for valuing and classifying over 5.6 million properties across the province and building an accurate property inventory.
MPAC’s products and services are key for government programs, business decisions, and property transactions. Municipalities use MPAC assessments to power local investments in important services like emergency services, libraries, water, and roads. Their data also helps identify property changes and market trends in Ontario’s communities to inform decisions about future developments. With over 1,700 full-time employees geographically dispersed across Ontario and a sizable, unionized employee base, MPAC has been recognized as one of Greater Toronto’s Top Employers since 2020.
