| | Delivering value: 2025 Property Assessment Notices and Assessment Rolls | | |
In November, we issued over 618,000 Property Assessment Notices to property owners throughout Ontario. These notices reflect updates resulting from the assessment of newly constructed properties, additions and/or renovations of existing properties, ownership transfers, school support selection, or changes in property use.
“The $41 billion in new assessment we captured represents nearly $30 billion from residential homes and $6 billion from commercial and industrial properties,” said Greg Martino, Vice President and Chief Valuation and Standards Officer. “We continue to see assessment growth led by residential and condominium development across the province.”
The total assessed value of Ontario’s more than 5.7 million properties is now estimated to be over $3.2 trillion, based on the assessed values as of January 1, 2016. The additional assessment is included in the annual assessment rolls delivered to Ontario’s 444 municipalities.

Meet Brian Guerin, Director of Assessment Standards and Mass Appraisal with the Valuation and Assessment Standards Department. Brian holds the Fellow of the Royal Institution of Chartered Surveyors (FRICS) designation with the Royal Institution of Chartered Surveyors (RICS) and holds a M.I.M.A. Designation from the Institute of Municipal Assessors (IMA).
Can you tell us a bit about yourself?
I’ve worked in property assessment for more than 30 years. During my career, I have led teams responsible for the mass appraisal of Ontario’s property inventory. Central to our work in mass appraisal is the development of state-of-the-art computer-assisted mass appraisal (CAMA) systems and conducting research initiatives.
| | |
What are some of the key areas of focus for you and your team?
Over the past several years, our team has presented at various industry events, sharing our work to modernize our mass appraisal processes. Our objective is to collaborate with others and continue to improve quality by leveraging the latest data science techniques and machine learning tools.
One of our current projects involves partnering with BC Assessment to test advanced modelling techniques with the goal of presenting our findings at the 2026 International Association of Assessing Officers (IAAO) annual conference in Calgary.
As a professional actively involved with the IAAO, how do you see Canada’s role in advancing global assessment practices?
Many of my colleagues at MPAC are involved with the IAAO and other professional organizations with the goal of sharing best practices that can be brought back to Ontario.
Currently, I am one of several Canadians who volunteer with IAAO committees. I presently serve as a member of the Research and Standards Committee and previously contributed to the Property Tax Policy and Administration (PTPA) Survey Task Force.
As valuation professionals, it is important that we continue to share knowledge, expertise, best practices and collective challenges. Being able to share my experience valuing properties across Ontario allows me to provide a unique perspective to these conversations. Our participation in these initiatives advances our work in Ontario and supports improved assessment practices across the profession, helping to build stronger and more resilient communities.
| | MPAC representatives continue to attend a variety of events and conferences to share best practices and connect with industry partners and representatives. | | Canadian Assessment Associations Summit: Valuing Canada’s Future | | |
The Canadian Assessment Associations Summit recently brought together assessment and valuation professionals from across the country to explore the trends shaping the valuation industry and Canada’s evolving market dynamics.
Greg Martino, Vice-President and Chief Valuation and Standards Officer at MPAC, chaired the keynote session featuring Stephen Poloz, former Governor of the Bank of Canada. John Sheppard, Director of Valuation Research and Advisory Services, contributed to a panel on Canada’s critical minerals sector, its implications for valuation and strategies for assessors to adapt to this rapidly changing resource economy.
This year’s virtual format enabled broad national networking and engagement while providing a forum to share best practices and explore emerging trends within the assessment community.

We look forward to connecting with our industry partners at conferences and events in the new year, including several property sector trade shows.
Join us online at the Institute of Municipal Assessors (IMA) and International Property Tax Institute (IPTI) Virtual Symposium, Embracing Global Innovation – Impact on Valuation Professionals, taking place January 27–28, 2026. Greg Martino, Vice-President and Chief Valuation & Standards Officer, will chair an engaging panel featuring experts from across Canada on the topic: Changing Skill Sets – Can AI Replace Property Valuers?
Our first tradeshow stop is National Golf Course Owners Association (NGCOA) Central and Southwestern Spring Warmups on March 3 and 4, 2026. We look forward to connecting with golf course operators and owners to gain market insights, discuss sector performance and our annual data collection campaign.
