In 2016, the Municipal Property Assessment Corporation (MPAC) updated the assessed values of every property in Ontario. These values were be used by the Municipality of Brockton to calculate your property taxes for the 2017-2020 property tax years.

Due to the COVID-19 pandemic new property assessments have been postponed. Property assessments for the 2022 and 2023 property tax years will continue to be based on January 1, 2016 current values.
