Assessed value of $797,000 on the record for 2026, asking $1,012,000, which is 27% above the assessed value, $5,628 of annual tax on the record for 2026, and $7,146 at the same rate on the price, $1,518 a year more, from the seeded demonstration record for this property. That record is this build's own arithmetic and not a bill a municipality issued.
What the tax line becomes at your price
Two numbers, and they are not the same number. The annual amount this record carries is what you will actually pay next year, because a sale does not trigger a reassessment in Ontario. What is projected below is the exposure if the assessment is ever trued up to what the house changes hands for.

This projection assumes a sale does not trigger a reassessment in Ontario, so your first bill after closing would be calculated on the assessed value already on file and not on what you paid.
It assumes general reassessment has stayed postponed since 2020 and that bills are still calculated on a January 1, 2016 valuation date. Confirm the current year with the municipality, because this is the assumption most likely to have changed.
It assumes that when reassessment resumes an increase is phased in over four years rather than applied at once, so the figure below is the end of a ramp and not the first bill.
The rate used here is back-computed from one assessment and one annual tax amount on this record, and the three sentences above are this build's own description of how assessment and billing work, written from belief. Nobody here has read the Assessment Act, anything the provincial assessment body publishes, or a municipal tax by-law, so take all of it to the municipality before budgeting from it.
This assessment record is seeded demonstration data, not an MPAC record. Verify the assessed value and the bill on the municipal tax portal before budgeting from it.
Everything we hold about this property, dated
One ordered list, price movements and tax records together, because they are the same story told by two different offices. Each row says what it implies rather than leaving you to work it out from the numbers.

How this sits against the comparable solds
Priced 18% below comparable solds · on market 100 days
Our estimate is $1,231,875, in a range of $1,064,984 to $1,398,767, at low confidence. Weighted average of 2 recent comparable sales (median 4838 m away), each adjusted for living area, sale recency (~0.3%/mo market drift) and bedroom count, then weighted by proximity, recency and similarity. Confidence is low (2 comps, ±14% band). Illustrative estimate on seed data, not a licensed appraisal.
Each of these is a hole in the record rather than a finding about the house. They are listed because a conclusion drawn from a partial history is only as good as the reader’s knowledge of which part is absent.
One listing episode held
The record holds one listing episode. We cannot tell a property that has only ever been listed once from one whose earlier listings were never given to us, so treat the start date below as the beginning of our record rather than the beginning of the marketing.
