How is my London home assessed?

Your tax is calculated as assessed value × mill rate, not market value × mill rate. Ontario uses a public assessment authority (BC Assessment, MPAC in Ontario, etc.) to set assessed values, usually updated every 1-4 years. Assessed value typically lags market value, so the same mill rate produces different effective burdens depending on assessment cycle timing.

Are London property taxes deductible on my income tax return?

Property tax on your principal residence is NOT deductible federally or provincially. It only becomes deductible when the property generates rental income (line 9180 on T776) or self-employed business income (CCA / business-use-of-home on T2125). For a principal residence, the tax is a non-deductible cost of ownership.

Why does London's mill rate differ from neighbouring cities?

Each Canadian municipality sets its own residential mill rate to fund local services — police, fire, transit, parks, road maintenance — plus a provincially-set education portion. Cities with higher assessed values can raise the same revenue at a lower mill rate (Vancouver, Toronto), while cities with lower assessed values often need higher rates to fund equivalent services.
