Measured tools (12)

• mortgage_payment read-only

  Calculate the periodic mortgage payment for a Canadian home. Call it ONE of two ways: (a) if the user gave a PURCHASE PRICE, pass homePrice + downPayment and CMHC insurance is applied when the down payment is under 20%; (b) if the user gave a MORTGAGE / LOAN AMOUNT (e.g. "payment on a $500,000 mortgage"), pass loanAmount on its own. Do NOT invent a purchase price in order to reach a loan amount — use loanAmount. Inventing a price changes the answer by several percent and attaches a CMHC premium the user does not owe.

  Parameters:

  • annualInterestRatePct (required) — number — Annual interest rate as a percent, e.g. 5.25
  • province — string — Province name, used only for CMHC PST on the premium
  • rateType — string
  • homePrice — number — Purchase price in CAD, e.g. 650000. Use with downPayment. Omit if the user gave you the mortgage amount instead.
  • termYears — number
  • loanAmount — number — The mortgage amount itself in CAD, when the user stated the loan rather than the purchase price. Mutually exclusive with homePrice. No CMHC premium is applied on this path — the amount is taken as the principal.
  • downPayment — number — Down payment amount in CAD (or percent if downPaymentType='percent'). Required when homePrice is used.
  • downPaymentType — string
  • paymentFrequency — string
  • amortizationYears — number — Amortization in years (max 25 insured, 30 uninsured/first-time new builds)

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• minimum_down_payment read-only

  Calculate the minimum down payment for a Canadian home under the Dec 2024 CMHC rules (5% on the first $500k, 10% on the portion from $500k–$1.5M, 20% at/above $1.5M), plus whether CMHC insurance applies and the premium rate.

  Parameters:

  • homePrice (required) — number — Purchase price in CAD, e.g. 800000

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• land_transfer_tax read-only

  Estimate land transfer tax on a home purchase for all 13 provinces and territories (incl. Toronto MLTT, Montreal welcome tax), first-time buyer rebates, plus the transfer registration fee (the government fee to register the deed) and the total due at registration. Alberta, Saskatchewan, Newfoundland & Labrador and the three territories charge no land transfer tax, only the registration fee. The mortgage registration fee is separate and not included.

  Parameters:

  • price (required) — number — Purchase price in CAD
  • province (required) — string — Province or territory
  • inToronto — boolean — Ontario only: property is within the City of Toronto (adds the municipal LTT)
  • isFirstTimeBuyer — boolean
  • quebecMunicipality — string — Quebec only: 'montreal' uses Montreal's welcome-tax brackets (the website's Quebec default); 'other' uses the provincial base schedule for municipalities without higher rates above $500,000

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• income_tax read-only

  • annualIncome (required) — number — Gross annual employment income in CAD
  • province (required) — string — Province of residence

• mortgage_penalty read-only

  Estimate the penalty to break a Canadian mortgage: three months' interest vs the interest rate differential (IRD), including the big-bank posted-rate method. Fixed = greater of the two; variable = usually three months' interest. IMPORTANT: the three rate inputs below are lender-specific and are NOT supplied by most users. If they are omitted, this tool falls back to illustrative site defaults and the answer can be several times too low or too high — the response reports exactly which values were assumed in `assumedInputs`. Always surface those assumptions to the user and tell them to confirm the real figures with their lender.

  Parameters:

  • balance (required) — number — Outstanding mortgage balance in CAD
  • contractRatePct (required) — number — Your contract rate as a percent, e.g. 5.25
  • monthsRemaining (required) — number — Months remaining in the term
  • rateType — string
  • lenderMethod — string — Big banks use the posted-rate IRD, monolines use actual rates. Which is larger depends on the gap between the discount originally received and today's posted rate — it is NOT always the big bank.
  • postedAtOriginationPct — number — Big-bank method: posted (not discounted) rate when you signed, from your mortgage documents. HIGH IMPACT — this single value can change the penalty several-fold. Omit if unknown and the reply will say it was assumed.
  • todaysPostedForClosestTermPct — number — Big-bank method: your lender's posted rate today for the closest term. Omit if unknown and the reply will say it was assumed.
  • currentRateForRemainingTermPct — number — Monoline method: today's rate for the remaining term (percent). Lender-specific — omit if unknown and the reply will say it was assumed.
