Property taxes are calculated using your property value as assessed by the Municipal Property Assessment Corporation (MPAC).
Every four years MPAC will update the assessed values of each property in Ontario and any increases are phased in over the four year period. The current assessed values are based on values as at January 1, 2016. Property assessment notices were mailed to property owners in 2016 with assessment information for taxation years 2017-2020. If you need a copy of the current assessment information for your property contact MPAC or visit www.aboutmyproperty.ca.
Assessment Update Postponed
The Municipal Property Assessment Corporation (MPAC), responsible for assessing property values in North Grenville, has announced that property assessments for the 2022 and 2023 tax years will continue to reflect a January 1, 2016 valuation date.
This does not mean property holders will not receive a property assessment notice. If you recently moved or made changes to your property you will receive a notice. The reason for the notice will be provided and can include:
• new property
• update to ownership
• change in assessed value
• change to tax classification
Read the MPAC News Release HERE.
Request for reconsideration
If you believe that your assessment is incorrect, you should first contact MPAC to discuss your assessment and verify details about your property. Further information is available on the MPAC website or by calling 1-866-296-MPAC (6722).
Please note that taxes must be paid by the due date even if you are appealing your assessment. The Municipality of North Grenville has no authority to cancel interest beyond the amount of tax reduction achieved if your appeal is successful.
To help provide clarity for property owners on how property taxes are calculated, including the link between property assessment, municipal service costs, and required tax dollars, watch MPAC’s helpful and informative new video below.
If you have built a new house on your property or made any significant change to the property, you can expect to receive a supplemental bill in addition to the original bill. This billing will take place after the Municipality receives notification from MPAC of the revised assessed value of the property.
The Municipality can register properties that are two years in arrears under the Municipal Tax Sales Act. Be sure to have all property tax arrears paid by the end of the year to avoid registration for tax sale.
