Assessment Appeal

May 22, 2025


What is an Assessment Appeal?

An assessment appeal is the formal process by which a property owner challenges the assessed value of their property as determined by a municipal or provincial authority.

Why Assessment Appeals Matter in Real Estate

In Canada, assessed values are used to calculate property taxes. If a homeowner believes their assessed value is too high or based on incorrect information, they may file an appeal.

Assessment appeals may be filed when:

  • The assessed value exceeds the home’s market value
  • There are factual errors (e.g., wrong square footage)
  • Comparable properties are assessed lower

The process typically involves:

  • Reviewing the assessment notice
  • Filing a formal appeal by the deadline
  • Presenting evidence (e.g., sales data, appraisals)
  • Attending a hearing or review board meeting
Successful appeals can lower property taxes. However, appealing does not always guarantee a reduction and may require time and documentation. Understanding how to appeal ensures fair taxation and helps homeowners hold municipalities accountable for valuation accuracy.

Example of an Assessment Appeal in Action

A homeowner in Ottawa files an assessment appeal after discovering nearby homes with similar features are assessed $50,000 lower.

Key Takeaways

  • Challenges a property’s assessed value.
  • Filed through municipal or provincial authorities.
  • Requires evidence and a formal process.
  • Can lead to reduced property taxes.
  • Must be submitted before deadlines.

What Would A G7 Of Housing Look Like?

What Would A G7 Of Housing Look Like?
Shutterstock

As world leaders gather in Canada for the G7 Summit, they’ll be talking about the big topics: global security, climate change, innovation, and economic resilience. These are critical issues, no doubt, but one of the most pressing challenges of our time will barely make the agenda: the housing crisis. From Toronto to Tokyo, Paris to San Francisco, housing affordability is deteriorating. Rents are rising faster than wages, homeownership is increasingly out of reach, and even middle-income earners are struggling to stay in the cities they work in. The crisis is no longer local — it's global. And yet, it still lacks the coordinated response we see in other international challenges.

We treat housing as a local issue, managed by cities and provinces — but what if we didn’t? What if we approached housing with the same level of international urgency, cooperation, and learning as we do other G7 priorities?

After surging 30% month over month in April, the seasonally adjusted annual rate (SAAR) of housing starts remained more or less flat between April and May with a 0.2% drop, as homebuilding in markets in Ontario and BC continued to weaken.

In the longer term, the six-month trend in housing starts also remained relatively flat in May, posting a 0.8% increase and hovering at 243,407 units, while actual housing starts grew 9% year over year, from 21,814 units last May to 23,745 units.

Although Canadian housing markets didn’t get the bustling start to spring that lower interest rates at one point seemed to promise, new national data shows that May brought a slight rally in activity. According to the Canadian Real Estate Association (CREA), sales edged up 3.6% between April and May, marking the first rise since November.

“May 2025 not only saw home sales move higher at the national level for the first time in more than six months, but prices at the national level also stopped falling,” said CREA Senior Economist Shaun Cathcart in a press release. To Cathcart’s point, the national composite home price index slipped just 0.2% month over month, “on the heels of three straight month-over-month declines of closer to 1%.”
