Will everyone get a Notice of Assessment this year?

It depends.

Normally, only properties that have a change in their assessment due to changes to the property (such as building or demolishing a house) or changes in tax classification (such as switching from residential to commercial use) will receive a Notice of Assessment.

However, as directed by the provincial government, a province wide revaluation of all properties is to be held every four years. 2021 is a revaluation year and so everyone will receive an updated Notice of Assessment this year.
