claim-001
RegulationTier A

Canadian fixed-rate mortgages compound twice a year (semi-annually, not in advance), which is the rule the calculator uses to convert the posted annual rate to an effective monthly rate.

Conditions for the claim to hold
Applies to fixed-rate mortgages on real property in Canada
Variable-rate products and HELOCs are typically compounded monthly under their separate contract terms; the calculator targets fixed-rate renewal scenarios
Inference logic
Section 6 of the Interest Act mandates that interest on money secured by mortgage on real property be calculated 'yearly or half-yearly, not in advance.' Canadian chartered banks and federally regulated lenders implement this as semi-annual compounding for fixed-rate mortgages. The calculator applies this rule directly when converting the posted nominal annual rate to an effective monthly rate.

Conditions for the claim to hold
Applies to fixed-rate Canadian mortgages with monthly payment frequency
For weekly or bi-weekly schedules, replace the 2/12 exponent with 2/52 or 2/26 respectively; the calculator uses 2/12 because it presents monthly outputs
Math / extrapolation
$Inputs nominal_annual_rate_r posted annual rate, percent (e.g. 4.19%) ✓ User-supplied input; the formula is rate-agnostic compounding_periods_per_year 2 (semi-annual) ✓ claim-001 Interest Act s. 6 mandate payments_per_year 12 (monthly) ✓ Standard Canadian monthly-payment convention; calculator targets monthly schedules Formula Step 1: semi-annual periodic rate r_semi = r / 2. Step 2: per-period growth factor over a half-year is (1 + r_semi). Step 3: equivalent growth factor over one month is (1 + r_semi)^(2/12) (because there are 2/12 = 1/6 of a half-year in a month). Step 4: effective monthly rate i = ((1 + r/2)^(2/12)) - 1. Result i = ((1 + r/2)^(2/12)) - 1, where r is the nominal annual rate expressed as a decimal Source of formula Interest Act s. 6 mandates the half-yearly compounding REQUIREMENT (statutory). The conversion formula i = ((1 + r/2)^(2/12)) - 1 is the standard mathematical implementation given that compounding rule, derived from the universal compounding-frequency-equivalence identity. The formula is not statutory text; it is the canonical math used by Canadian chartered-bank amortization engines to honour the Interest Act s. 6 mandate.$
Inference logic
DERIVATION CHAIN: (1) compounding rule from claim-001 -> Interest Act s. 6 mandates Canadian fixed-rate mortgage interest 'calculated yearly or half-yearly, not in advance' (statutory verbatim, primary source). (2) -> conversion formula -> given the statute mandates semi-annual compounding (2 periods per year), the equivalence transformation to a monthly-compounded effective rate uses the universal identity (1 + i_target)^periods_target = (1 + i_source)^periods_source. Setting periods_target = 12 (monthly) and periods_source = 2 (semi-annual mandated by statute) yields i = ((1 + r/2)^(2/12)) - 1. The statute is the foundational anchor; the conversion formula is one inference step (the universal time-value-of-money math) on top of the statutory compounding rule. The source_quote 'calculated yearly or half-yearly, not in advance' is the foundational regulatory anchor for the whole chain; the formula itself is universal mathematics, not statutory text.

The calculator JS computes x = (1+i)^n then returns B * (i * x) / (x - 1). Result Monthly payment P that fully amortizes balance B over n monthly periods at effective monthly rate i Source of formula Canonical present-value-of-annuity identity. Universal mathematical convention; not statutory. The Canada-specific input is the effective monthly rate i, computed via the Interest Act s. 6 half-yearly compounding rule (claim-002 carries the statutory citation); the amortization identity itself is universal mathematics and not defined by any Canadian statute.$
Inference logic
The amortization identity P = B * i / (1 - (1+i)^-n) is universal mathematical convention derived from the present-value-of-annuity formula. It is not statutory. The Interest Act s. 6 governs how the effective rate i must be computed for Canadian mortgages (half-yearly compounding) but does not define the amortization formula itself. Honest framing: the formula is mathematical, not regulatory; the only Canadian-specific element is the upstream rate-conversion step in claim-002.

Conditions for the claim to hold
Mortgage default insurance premiums apply only to high-ratio (less than 20% down) purchase transactions, not refinances (since 2016 withdrawal) or most renewals where the loan is not increased
Property taxes and condo fees are typically itemized separately by lenders even when bundled into a combined payment; they do not affect the underlying interest math
Inference logic
Naming the three Canadian default insurers (CMHC, Sagen, Canada Guaranty) is a factual statement about the federally regulated insurer roster. The calculator's scope statement is accurate: it computes principal-and-interest only, not the bundled PIT (principal-interest-taxes) or PIT-plus-insurance figures some lenders display. This is the standard scope for renewal-payment-shock calculators; including taxes and insurance would require additional inputs the calculator does not collect.

2026-05-01 · ITER-28 FINAL: claim text reduced to qualitative existence statement that the CMHC page heading literally supports.
2026-05-01 · ITER-28 FINAL: SQ updated to literal CMHC page title. Claim text aligned to what the title supports.

Part 1 of 1
What this verifies: FCAC encourages shopping multiple lenders at renewal
Source: Renewing your mortgage · Financial Consumer Agency of Canada · link
Tell your lender about offers you received from other financial institutions or mortgage brokers. You may need to provide proof of the offers you receive.
✓ matches page
FCAC instructs borrowers to bring competing offers to the renewal conversation. The phrase 'shop around' is FCAC's own consumer-guidance framing across mortgage pages.

Conditions for the claim to hold
Lender count varies by brokerage and broker; some specialty brokerages have access to fewer (15-20) but with deeper relationships, others have 40+
Rate improvement at renewal depends on file quality (credit, income, equity), market timing, and lender appetite
Inference logic
FCAC's renewal page encourages shopping around without specifying a number of quotes or a percentage of borrowers who do so. Specific 'three to five quotes' or '30 per cent of Canadians shop' figures were editorial synthesis without primary source. Demoted to qualitative.

2026-04-30 · Initial entry. FCAC anchors the regulatory recommendation; broker-channel lender count is industry pattern (Tier C-leaning) but elevated to Tier B because every major national brokerage publishes equivalent claims of '30+ lenders' on their own marketing pages, which constitutes corroborated industry data.
2026-04-30 · Marked verbatim_check=false; 'shop around' verifies FCAC recommends shopping but does not verify the specific 3-5 / 30+ lender figures (which are industry-pattern synthesis already documented in inference_logic). Per editor fact-check feedback on the source-quote-vs-specific-claim fallacy.
2026-05-01 · ITER-14 FIX: demoted. Original cited '3-5 quotes' and '30+ per cent' specifics with 'shop around' two-word verbatim. Demoted to FCAC's qualitative shopping-around encouragement. Article body must drop the 3-5 / 30+ specifics.
2026-05-01 · ITER-27 FIX: decomposed with full FCAC verbatim instructing borrowers to surface competing offers at renewal.

Evidence (per sub-claim)

Part 1 of 1
What this verifies: Calculator processes inputs entirely in the browser; nothing is transmitted, logged, or saved
Source: Renewal payment calculator (RenewalRate.ca) · RenewalRate.ca · link
All math happens in your browser
✓ matches page
The calculator page's privacy callout is the canonical source for the data-handling behaviour. The page does not include any form-submit endpoint that would transmit inputs.

Conditions for the claim to hold
PRECISION FLAG: the FAQ's 'No inputs are sent to any server' is technically narrowly inaccurate because the affiliate-click handler at calculator.html line 819-840 transmits currentRate, newRate, and balance to Zaraz when the CTA is clicked. Recommend tightening the FAQ wording to 'No inputs are sent unless you click an affiliate CTA, and even then only to our own analytics for attribution; nothing is sent to any third party other than our analytics provider.'
Server-side: Cloudflare Pages logs HTTP request metadata (IP, path, user-agent) for any visit; this is standard hosting infrastructure, not application-level data collection
Inference logic
Inspection of calculator.html confirms: (1) all five input fields wire to a JS compute() function that runs in-page; (2) the only network calls in the JS are gtag pageview tracking, font preconnect, and the affiliate-click handler (which fires only when the user clicks the Homewise CTA, and even then transmits only partner/placement/timestamp/gclid metadata to Zaraz, not the calculator inputs as PII); (3) no fetch, XHR, or form-POST of the input values exists in the source. Caveat: balance/currentRate/newRate ARE included in the affiliate_click Zaraz payload IF and only IF the user actively clicks the Homewise CTA. The 'no inputs are sent' claim therefore holds for the calculator-use flow, but a precise rendering would say 'no inputs are sent until you choose to click an affiliate link, at which point the rate inputs may be passed to our analytics for funnel attribution.'

2026-04-30 · Initial entry. Verified by inspection of calculator.html source. Precision discrepancy flagged: affiliate-click handler transmits rate inputs and balance to Zaraz analytics when CTA is clicked; FAQ wording should be tightened to acknowledge this conditional path.
2026-05-01 · ITER-27 FIX: demoted multi-fact privacy assertion. 'Server / database / third party' specifics stripped because the on-page callout uses 'happens in your browser' framing only.

Conditions for the claim to hold
Licence is for Ontario operations; Homewise also operates in other provinces under the equivalent provincial regulators (BCFSA, AMF, FCAA, FCNB) but #12984 specifically anchors the Ontario authorization
Inference logic
FSRA #12984 is the Homewise Solutions Inc. brokerage licence number on file in the FSRA registry as of the partnership signing date (2026-04-27). FSRA is the provincial regulator for Ontario mortgage brokerages, established under the Mortgage Brokerages, Lenders and Administrators Act, 2006 (MBLAA). The licence is on the public FSRA registry which is the canonical source of truth for Ontario mortgage brokerage licensing.

2026-04-30 · Initial entry. Licence number cross-referenced in the partnership agreement (signed 2026-04-27) and the agent's own knowledge base. Recommend annual re-verification against the FSRA registry to catch any licence status changes.
2026-04-30 · VERBATIM MISMATCH: source_quote not found on rendered page during screenshot capture. May indicate paraphrase, page change, or required tab navigation. Review needed.
2026-04-30 · Source URL replaced. fsrao.ca registry-search URL returned 404 to non-browser fetches; canonical searchable registry is mbsweblist.fsco.gov.on.ca/agents.aspx (FSCO/FSRA legacy public listing). Source_quote anchored on the page title verbatim. Wayback URL updated.
2026-05-01 · ITER-14 FIX: parallel to ird-023, switch-018.
2026-05-01 · ITER-24 LINT FIX: prior FSRA registry URL returned 404 (no stable per-licensee URL exists). Specific 'Licence #12984' assertion demoted out of claim text because no public stable URL carries it as a verbatim. Claim now anchors to the Homewise partner page that does resolve. License-number verifiability moves to attestation tier (pending Homewise FSRA-licensed staff sign-off).
2026-05-01 · ITER-27 FIX: same Homewise demote as ird:claim-023.
