Disclosure – 2016 Assessment Update

Advanced Disclosure Image

Disclosure is about transparency and shared understanding. It’s about our commitment to share information with property owners and stakeholders and provide fair, consistent and accurate property valuations through a no-surprise approach.

The initiative supports MPAC’s 2013-2016 Strategic Plan, delivery of the 2016 Assessment Update and aligns with the recommendations made in the Ministry of Finance’s Special Purpose Business Property Assessment Review (SPBPAR) Report.

What are the three levels of Disclosure?

MPAC’s disclosure activities in support of the 2016 Assessment Update include three levels of information that will be shared with taxpayers and municipalities. They consist of:

Level 1 - Methodology Guides

Comprehensive guides that explain assessment methodology.

Level 2 - Market Valuation Reports

Comprehensive reports that explain how assessment methodology was applied at the sector level to value properties for the 2016 Assessment Update.

Level 3 - Property Specific Valuation Information

Detailed information that is available through secure‐access only or upon written request from taxpayers, representatives and/or municipalities.
