Municipal Property Tax Rates 2014

Municipal tax rates for each of Lambton County's eleven municipalities are generally set by each municipality during the 1st or 2nd quarter of the year. Municipal property taxes for commercial, industrial and residential sites are calculated according to property values determined by the Ontario Property Assessment Corporation. Assessment values are multiplied by the applicable tax rate for each class of property.

The following is a sample calculation of annual property taxes on an Industrial property with an assessed value of $1,000,000. For this example the tax rate is 4.166532 per cent:
Assessed Value – $1,000,000 / Total Taxation = $1,000,000 X .04166532 = $41,665.32
