Tool Tokens
acheter_ou_louer ~152

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.

NameTypeReqDescription
villestringyesCity, e.g. "Montréal", "Toronto", "Winnipeg".

No output schema declared.

No examples provided.

contacter_expert ~350

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.

NameTypeReqDescription
client_courrielstringyesEmail address of the user — the expert will reply there.
client_nomstringyesFull name of the user requesting contact.
client_telephonestringOptional phone number of the user.
consentementbooleanyesMUST be true, and only after the user explicitly approved sending this request to this specific expert.
messagestringyesThe user’s request in their own words (need, property, timeline…), 20–2000 characters.
professionstringyesreal-estate-broker | mortgage-broker | home-inspector | notary-lawyer | appraiser (French labels accepted).
provincestringProvince name or code (optional disambiguator).
secteurstringNeighbourhood/sector of the expert (recommended — identifies exactly one expert).
villestringyesCity of the expert, e.g. "Montréal".

No output schema declared.

No examples provided.

salaire_requis ~177

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.

NameTypeReqDescription
prixnumberOptional price in CAD to test instead of the city’s reference price.
villestringyesCity, e.g. "Montréal", "Vancouver", "Halifax".

No output schema declared.

No examples provided.

stats_marche ~96

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. Compiled by Payotte from real-estate board and CREA publications; each city lists its sources.

NameTypeReqDescription
villestringyesCity, e.g. "Montréal", "Ottawa", "Vancouver".

No output schema declared.

No examples provided.

taux_courants ~100

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). Read live from the Bank of Canada (Valet API); each rate 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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

taxe_mutation ~191

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.

NameTypeReqDescription
prixnumberPurchase price in CAD. Omit with a ville to use the city’s reference market price.
provincestringProvince name or code — required if no ville is given.
villestringCity, e.g. "Toronto", "Montréal", "Calgary". Determines the schedule AND the default price.

No output schema declared.

No examples provided.

trouver_expert ~305

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").

NameTypeReqDescription
professionstringOne of: real-estate-broker | mortgage-broker | home-inspector | notary-lawyer | appraiser (French labels accepted: courtier immobilier, courtier hypothécaire, inspecteur en bâtiment, notaire, évaluat…
provincestringProvince name or code, e.g. "Québec", "ON", "british-columbia".
secteurstringNeighbourhood/sector, e.g. "Le Plateau-Mont-Royal", "Ville-Marie".
villestringCity, e.g. "Montréal", "Toronto", "Calgary".

No output schema declared.

No examples provided.

verifier_titre ~130

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.

NameTypeReqDescription
professionstringyesreal-estate-broker | mortgage-broker | home-inspector | notary-lawyer | appraiser (French labels accepted).
provincestringProvince name or code. Omit to get every province for that profession.
