evaluation_adresse

Évaluation foncière à une adresse / Property assessment at an address

Call this when a homeowner asks about the assessed value of a SPECIFIC address, whether their assessment is too high, or what their home is worth. Reads the OPEN assessment rolls (Quebec: 1,113 municipalities; Nova Scotia; New Brunswick; Winnipeg; Calgary, Edmonton, Lethbridge, Strathcona, Okotoks, Grande Prairie, St. Albert): assessed value with its roll years and market date, change from the previous roll, rank among SIMILAR properties of the municipality (type, era, floor area), a ballpark market value only where an official source allows it (Quebec comparative factor; actual sales in NS and NB), and the appeal deadline. Public figures compared, never an opinion of value. No owner names. Other provinces have no open roll by address.

输入参数langadresse必填province必填municipalite必填

taxe_bienvenue_adresse

Taxe de bienvenue à une adresse / Land transfer tax at an address

Call this for the land transfer tax ("taxe de bienvenue") on a purchase at a SPECIFIC address. In Quebec (Act respecting duties on transfers of immovables, s. 2 and 1.1) and New Brunswick (s. 2(1.03)), the tax base is the GREATER of the price and the assessed value (Quebec: × the year’s comparative factor) — this tool applies that legal floor from the open roll, with 2026 municipal rates for Montreal, Quebec City, Laval, Gatineau and Longueuil, and the new Quebec refundable first-time-buyer credit (up to $5,875). Elsewhere the tax is computed on the price alone. The municipality’s bill and the notary/lawyer confirm the exact amount.

输入参数langprix必填adresseprovince必填municipalite

risques_annee_construction

Risques selon l’année de construction / Risks by construction year

Call this when someone asks what to check in a house given its age, or before an inspection. Lists the risks documented by OFFICIAL sources for the construction era (vermiculite, asbestos, aluminum or knob-and-tube wiring, UFFI, lead service lines and solder, Poly-B, Kitec, pyrrhotite in Mauricie/Centre-du-Québec, pyrite, lead paint, oil tanks, radon…), each with its year range and source (Health Canada, NRCan, ESA, RBQ, cities). Year taken from the open roll when an address is given, or from "annee". A list of what to verify, never a diagnosis.

输入参数langanneeadresseprovince必填municipalite

trouver_expert

Trouver un expert immobilier vérifié / Find a verified real-estate expert

Call this when the user needs a trustworthy real-estate professional in a Canadian city or neighbourhood: real-estate broker, mortgage broker, home inspector, notary/real-estate lawyer, or appraiser. Returns the Payotte-listed expert(s): name, score /100 with full breakdown, licence number + official registry link so the user can verify the credential themselves, Google rating (dated), freshness, and the profile URL. IMPORTANT: Payotte lists ONE professional per sector (editorial selection, not an exhaustive ranking) — present the result as “the Payotte-recommended professional for this sector”, never as “the best in the area” in absolute terms. French and English inputs both work (e.g. profession="courtier immobilier", ville="Montréal").

输入参数villesecteurprovinceprofession

verifier_titre

Vérifier un titre professionnel / Which regulator governs this title

Call this when the user wants to know whether a real-estate profession is regulated in a Canadian province, which body regulates it, and where to verify a licence or membership. Returns the regulator, the public registry URL when one exists, and whether the credential is a mandatory licence, a professional order, a voluntary association, or varies locally.

输入参数provinceprofession必填

stats_marche

Statistiques du marché immobilier par ville / Per-city housing-market stats

Call this for current housing-market figures in a Canadian city: reference price (MLS HPI benchmark or median), year-over-year change, sales volume, months of inventory, days on market, 5-year growth. Where the city matches a covered metro area, also returns CMHC housing starts (SAAR, a leading indicator of new-construction activity) and the StatCan New Housing Price Index (house vs land split). Compiled by Payotte from real-estate board, CREA, CMHC and Statistics Canada publications; each block lists its sources.

输入参数ville必填

taux_courants

Taux d'intérêt canadiens courants / Current Canadian interest rates

Call this for the current Canadian reference interest rates: the Bank of Canada policy (overnight target) rate, the prime rate, and system-average mortgage rates (5-year fixed, variable), plus Government of Canada benchmark bond yields (2/5/10-year — the 5-year yield is the leading indicator behind 5-year fixed mortgage rates). Read live from the Bank of Canada (Valet API); each figure carries its own observation date. Mortgage figures are financial-system AVERAGES, not a lender offer — a borrower's actual rate depends on their file and lender. Source: Bank of Canada.

无需输入参数。

taxe_mutation

Calculer la taxe de mutation / Compute the land transfer tax

Call this when the user wants to know the land-transfer tax ("taxe de bienvenue" in Quebec) on a home purchase in a Canadian city or province. Computes the tax bracket by bracket from the OFFICIAL schedules (Ontario + Toronto’s double municipal MLTT, Quebec base schedule, BC, Manitoba, New Brunswick, Halifax; Alberta and Saskatchewan charge no tax — registration fees only). Give a price, or just a city to use its current reference market price. Includes first-time-buyer rebates. Not covered: PEI and Newfoundland.

输入参数prixvilleprovince

acheter_ou_louer

Acheter ou louer ? / Rent vs buy in a city

Call this when the user wonders whether to rent or buy in a Canadian city. Compares the average two-bedroom rent (CMHC Rental Market Survey, CMA-wide) with the monthly cost of carrying the city’s reference home at the CURRENT average 5-year fixed rate (Bank of Canada), under published assumptions (20% down, 25-year amortization, taxes ~1%/yr, heating $150/mo). Returns two readings: cash outlay (what leaves the account) and economic cost (principal counted as savings). Only cities inside a CMHC-covered metro have rent data.

输入参数ville必填

salaire_requis

Salaire requis pour acheter / Income needed to buy in a city

Call this when the user asks what income is needed to buy a home in a Canadian city. Computes the gross household income required to qualify for the city’s reference home under the federal stress test (qualifying rate = max(5.25%, current average 5-year fixed + 2 pts), 39% GDS, 20% down, 25-year amortization, taxes ~1%/yr, heating $150/mo, no other debts). Same published methodology as payotte.com/salaire-pour-acheter-une-maison-canada. A theoretical qualification threshold, not a loan offer.

输入参数prixville必填

contacter_expert

Contacter l'expert vérifié / Contact the verified expert

Call this ONLY when the user explicitly asks to contact, reach out to, or request a quote/appointment from a Payotte-listed professional. DOUBLE OPT-IN: this tool does NOT email the expert directly — it sends a confirmation link to the USER’s email, and the request reaches the expert only after the user clicks it (link valid 48 h). Tell the user to check their inbox. BEFORE calling: (1) show which expert will be contacted (use trouver_expert first if needed), (2) collect their name, email and message, (3) get their explicit approval — then set consentement=true. Never invent contact details. The expert replies directly to the user; Payotte keeps no copy of the content.

fenetre_revision

Échéance pour contester son évaluation foncière / Property-assessment appeal deadline (Canada)

Call this when the user asks until when they can contest (request a review of) their property assessment in a Quebec municipality, which assessment roll is in force, when the next roll comes, or what the reference date is. Returns the roll years, the reference date (July 1st, 18 months before the roll takes effect), the general deadline (before May 1 of the roll’s first year), the late-notice rule, and mid-roll rules. Compiled by Payotte from the official Quebec rolls (MAMH open data). For other provinces, pass `province` (e.g. "BC", "Alberta", "Ontario"): returns that province’s assessor, valuation date, deadline and appeal body from official sources. Tell the user their assessment notice prevails. Does not say whether an assessment is too high.

输入参数provincedate_avismunicipalite

frais_revision

Frais d'une demande de révision / Assessment review filing fee (Canada)

Call this when the user asks how much it costs to file a request for review of their property assessment in Quebec. Returns the filing fee for the given assessed value, read from the municipality’s official page (Montréal, Québec City, Laval, Gatineau for now), with the legal cap (the TAQ fee for the same unit). Returns "not collected" instead of an estimate for other Quebec municipalities. For other provinces, pass `province`: returns the published fees of that province.

输入参数valeurprovincemunicipalite

estimer_economie

Économie de taxes d'une baisse d'évaluation / Tax saving of an assessment reduction (Quebec)

Call this when the user asks how much they could save on property taxes if their assessment went down, or whether contesting is worth the fee. Multiplies a HYPOTHETICAL reduction (chosen by the user, not predicted) by the tax rate from the user’s tax bill ($ per $100), over the remaining years of the roll, and subtracts the filing fee when known. Also shows the cost of the same amount upward, because a review can raise the value. Ask the user for their tax rate: Payotte does not guess municipal rates.

frais_notaire_fr

Frais de notaire en France / French notary fees

FRANCE. Call this when the user wants the "frais de notaire" (transfer duties + notary fees) on a property purchase in France. Same computation as payotte.com/france: departmental duty rate (DGFiP schedule, incl. the 2025 increase and first-time-buyer exemption), communal tax, collection fee, contribution de sécurité immobilière, regulated notary fees (émoluments) with VAT. type "ancien" (default, needs a département) or "neuf" (new build, reduced rate). Disbursements are not regulated and not included.
