Property Assessment and Taxation Toolkit
To better help property owners understand the relationship between property assessment and taxes, as well as the key roles different levels of government play, MPAC has developed a toolkit for municipalities and government partners to use. These resources include information and tools designed to help you educate property owners and answer any questions they might have.
In this kit you will find:
- Shareable content to post on your website, newsletters and social media channels.
- Printable handouts.
- Key messages about the relationship between property assessment and property taxes.
- Frequently asked questions to share with your customer service and frontline staff. This useful information is designed to support them in responding to inquiries they may receive from property owners.
- MPAC’s video on how property taxes are calculated.

Does a higher assessment mean higher property taxes?
A higher property assessment doesn't automatically mean your property taxes will increase by the same amount.
Property taxes are based on both your property's assessed value, determined by MPAC (Municipal Property Assessment Corporation), and your municipality's tax rate.
During a province-wide Assessment Update, what matters most is how your property's value changes compared to the average change for your property type in your municipality.

Does a higher assessment mean higher property taxes?
A higher assessed value does not automatically mean your property taxes will increase by the same amount. Property taxes are based on two key factors: your property's assessed value and the tax rates applied to it. MPAC (Municipal Property Assessment Corporation) determines assessed values. Municipalities determine the funding needed for local programs and services and set tax rates to collect those funds. Education tax rates are set by the Province of Ontario.
During an Assessment Update
An Assessment Update moves every property in Ontario to a new valuation date, so all values reflect the same point in the market.
What matters most is how your property's value changed compared to the average change for your property type in your municipality. If your value changed at close to that average, the Assessment Update itself does little to your share of municipal taxes. If it increased more than the average, your share could rise. If it increased less, your share could fall.
Between Assessment Updates
A property's assessed value can also change on its own. For example, after new construction, an addition or renovation, a change in how the property is used or classified, or a severance or consolidation. In these cases, the change reflects what happened to that specific property, so it can affect that property's taxes more directly.
Your final tax bill also depends on your municipality's budget decisions, which are made separately from the assessment process.
This is why a change in assessed value does not automatically result in the same change to your property tax bill.

Understanding property assessments
Property assessments and property taxes are connected, but they don't mean the same thing.
MPAC (Municipal Property Assessment Corporation) determines the assessed value and classification of properties across Ontario. Municipalities use this information to help determine each property's share of municipal taxes and to support their property tax system.
A property's assessed value is only one factor used to calculate property taxes. Tax rates set by your municipality and the Province of Ontario also play an important role.

Your tax bill
Your final tax bill also depends on your municipality's budget decisions, which are made separately from the assessment process. That's why a change in your assessed value does not automatically result in the same change to your property tax bill.

Option 1
A higher property assessment doesn’t automatically mean higher property taxes.
Property taxes are based on two things: your property's assessed value, determined by MPAC (@Municipal Property Assessment Corporation), and the tax rates set by your municipality and the Province of Ontario.
During a province-wide Assessment Update, what matters most is how your property's value changes compared to the average change for your property type in your municipality. If your value increased less than that average, your taxes could go down. If it increased more, they could go up.

Option 2
Property assessments and property taxes are connected, but they're not the same thing.
MPAC (@Municipal Property Assessment Corporation) determines a property's assessed value. Municipalities set tax rates based on local funding needs, then use assessed values to determine each property's share of municipal taxes. Education tax rates are set by the Province of Ontario.
That's why a change in your assessed value does not automatically result in the same change to your property tax bill.
