Large and Special Purpose Property Engagement

MPAC assesses all properties in Ontario every four years. We engage with large and special purpose property owners, affected municipalities and other stakeholders as part of our work to determine updated assessments for these properties across the province.

Our engagement efforts focus on bringing property owners, municipalities and stakeholders together with our assessors to:

  • Improve data collection;
  • Consult and collaborate on valuation methodologies and key valuation parameters;
  • Identify areas of risk within each respective industry; and,
  • Share preliminary values with property owners and municipalities to identify any concerns before roll return.

We are committed to providing opportunities for meaningful information exchange and engagement. Stay tuned for more information.
