Assessment is not the same as your tax bill
Your property assessment determines your share of the tax requirement. The City explains that bills reflect both municipal and provincial budget needs and your property’s assessed value. A change in assessment does not, by itself, tell you the percentage change in your final bill.
Municipal and provincial components
Use the City’s calculator to see the breakdown for your assessed value. This independent planner does not calculate official tax rates or replicate the City’s tool. Enter your actual bill, or an estimate obtained from the official calculator.
Find the right year and dates
Use the tax year shown on your assessment notice and bill. The City’s calculator identifies assessment notices as mailed in January and bills in May. Confirm the current payment deadline, penalties and review period directly on your notice and through official City information; no deadline is inferred here.
Paying and reviewing your bill
The City offers official information about payment options and support for people having trouble paying. Read the terms of any instalment plan before signing up. If an assessment seems incorrect, use the official assessment review process and confirm its deadlines instead of treating a budget estimate as grounds for a complaint.
Renovations and your ownership budget
Ask the City how a proposed property change may affect assessment. Separately, consider insurance, utilities, recurring fees and a maintenance reserve. These are personal planning inputs, not municipal tax calculations. The planner below keeps every estimate editable.
