Upper Joshua Creek Phase 6, Oakville: pricing from $958,398, and a deposit line that only goes halfway

By MyHomeDeals editorial · Published 2026-11-03 · Launch Breakdowns & Worksheets

Mattamy's Phase 6 record now carries a verified starting price for the Laurel plan, closings in 2026–2027, and a deposit structure that publishes the signing cheque but not the instalment amounts.

Some records earn a breakdown because they are complete. This one earns it because it is half complete in an instructive way: the price is now verified to the dollar, and the deposit structure still stops mid-sentence. Both halves matter before anyone registers.

The price, with its basis attached

Upper Joshua Creek Phase 6, by Mattamy Homes in Oakville’s Westoak Trails, is priced from $958,398 — after estimated rebate; eligibility applies. That figure is the published starting price of the Laurel plan on Mattamy’s own community page, verified November 3, 2026. The record’s price basis is after-rebate-enhanced: Mattamy states its prices include an estimated amount for the temporary Ontario enhanced new housing HST rebate, and the actual rebate varies by buyer and eligibility. Read the number as a plan’s starting price on a rebate-adjusted basis — not as a tax-in, all-in figure, and not as the entry price of every home type in the phase. The record covers townhouses and detached homes; the $958,398 belongs to the named plan it was published for.

Until this verification the record sat in the catalogue’s on-request pool with a price band instead of a number. It is one of four band-text records resolved to a builder-published figure in the November 3 verification pass; the other ten band records stayed on request, because a band is not a price and this catalogue does not convert one into the other.

What the deposit line says — and where it stops

The record’s deposit text, in full: detached homes pay $40,000–$50,000 on signing depending on lot width, with further instalments at 60, 120 and 180 days; townhome schedules are set by collection. That is a real signing range and a real instalment rhythm — and no instalment amounts, no total, and no percentage. A buyer can budget the first cheque from this record and cannot budget the next three. Compare that with a schedule like NOMI’s in Kitchener, where every step to 10% is published in dollars: the difference between the two records is not the builders’ generosity, it is how much of the cash path each has put in writing.

Detached homes: $40,000–$50,000 on signing depending on lot width, with further instalments at 60, 120 and 180 days (confirm terms with us). Townhome schedules are set by collection — ask us for the current one before you rely on it

The rest of the record

  • Timing: closings in 2026–2027 — a window, not a date, and the record keeps it that way.
  • Published incentives include a $0 cap on development-charge increases, free assignment (a stated $5,000 value; admin and legal fees apply), a design-studio credit of $15,000 on townhomes and $20,000 on detached homes, and detached price reductions of $40,000–$60,000 by lot width. Every one of these carries the record’s own instruction to confirm current terms; incentives are the line in any record most likely to have changed since it was published.
  • Location on record: Dundas St E & Ninth Line, Oakville.

The honest gaps

No floor plans are structured on this record yet, so it contributes nothing to Oakville’s per-bed comparisons — Oakville has priced records but no city in this catalogue gets a per-bed table until enough of its records carry verified plan data (Kitchener is the only one that does today). And the townhome deposit schedule does not exist in published form on the record at all: “set by collection” is the builder’s position, recorded as-is.

That is the breakdown the record supports: one verified price with its basis named, a deposit structure with the first cheque priced and the rest dated but unpriced, and a closing window. Everything beyond that is a question for the builder — which is exactly what the enquiry form on the project page is for.
