Property taxes are calculated by multiplying a tax rate, as set by the City of Thorold, by the property's assessed value. The Municipal Property Assessment Corporation (MPAC) is responsible for placing a value on all properties in Ontario. For more information concerning your assessment you can check there.

If the property you own is under construction, being renovated or is a newly constructed building, you may not be fully assessed.  If the change to the property was not picked up on the assessment roll by January 1st, you will be issued a supplementary tax bill(s).  MPAC can assess the current year plus previous two tax years for such changes.  This bill will be issued upon receipt of the necessary assessment information from the Municipal Property Assessment Corporation and may be payable in less than two instalments.

If you have recently purchased a home and have not received a tax notice prior to the due dates, please contact the Tax Department at 905-227-6613.
