The deposit that couldn’t exist

a Saint-Hyacinthe closing statement’s phantom credit

A Saint-Hyacinthe purchase's own statement of adjustments credited the buyer with a last month's rent deposit the seller was assumed to be holding. Quebec's Civil Code bars a landlord from ever collecting a deposit for a dwelling, so no such fund existed -- the buyer's real cash-to-close was $1,190 higher than the first draft showed.

Anonymized illustration. The borrowers, dollar figures, and rates in this file are an illustrative composite — no real client is identifiable, and any rate shown is illustrative, not a quote. The rules are real: every regulatory figure is cited to its source in the Sources section, and the math computes exactly as shown.

The client

A buyer is purchasing a $342,000 owner-occupied duplex in Saint-Hyacinthe, Quebec, with $34,200 (10%) down, planning to live in one unit and rent the other to a sitting tenant at $1,190/month.

The problem

The listing brokerage's template for the statement of adjustments -- borrowed from a common-law-province closing kit -- credited the buyer with a last month's rent deposit the seller was assumed to be holding, to be transferred at closing along with the tenancy itself. That is a routine adjustment in Ontario and most other provinces. It is not a routine adjustment in Quebec, because no such deposit is ever legally allowed to exist there in the first place.

What Quebec's Civil Code actually bars a landlord from doing

  • A landlord may not require a security deposit, a damage deposit, or any advance rent of any kind as a condition of leasing a dwelling
  • A landlord also can't require post-dated cheques covering the whole term of the lease -- rent is collected month by month
  • Because no deposit is ever legally collected, there is nothing for an outgoing landlord to hold, and nothing for a statement of adjustments to credit at closing

Confirming this with the notary meant the adjustment sheet's credit had to come out entirely -- not renegotiated to a smaller figure, removed, because the fund the credit assumed existed had never legally existed at all.

The numbers

Because this is an owner-occupied purchase with a rental unit, CMHC's standard homeowner schedule and rental-offset convention both apply as usual -- the deposit question never touched the ratios, only the cash actually needed at closing, a detail the broader rental vacancy data for Quebec doesn't track at all.

Sizing the mortgage, then correcting the cash-to-closeAmount
Base mortgage (price less down payment)$307,800
CMHC premium (3.10% at 85.01-90% LTV)+$9,542
Total insured mortgage$317,342
Quebec welcome tax (droits de mutation) on $342,000$3,240
Cash-to-close correction once the phantom deposit credit is removed+$1,190
Housing cost basisFigure
Qualifying payment at 7.05% (MQR on 5.05%)$2,233
Property tax, heat and the car loan$665
Rental offset (50% of $1,190)-$595
TDS ÷ $7,300 income31.5%

31.5% TDS confirms the ratios were never the issue on this file -- the entire correction was to the cash-to-close figure, once Quebec's no-deposit rule replaced an assumption borrowed from another province's closing practice, leaving the rental offset itself untouched.

The solution

A courtier hypothécaire (mortgage broker) licensed under Quebec’s Act respecting the distribution of financial products and services treated the deposit credit as a fact to verify against Quebec law, not a routine line item to accept from the listing's own paperwork.

First, had the notary confirm directly against the seller's own tenancy records that no security deposit or advance rent had ever been collected from the tenant -- consistent with Quebec's Civil Code, not an oversight by the seller or the outgoing landlord.

Second, corrected the statement of adjustments to remove the phantom credit entirely, rather than negotiate it down, since the fund the credit assumed existed had never legally existed in Quebec at all.

Third, confirmed the buyer's own cash-to-close with the corrected figure well before closing, so the extra $1,190 came as a documented correction rather than a surprise at the notary's office.

Seller's tenancy records confirming no deposit or advance rent was ever collected
Written confirmation from the notary of Quebec's no-deposit rule as it applies to this tenancy
Corrected statement of adjustments, with the phantom deposit credit removed
Updated cash-to-close figure confirmed with the buyer before closing
Insured mortgage commitment confirming the $317,342 total loan

The outcome

The purchase funded at $317,342 insured, 31.5% TDS with the rental offset applied, and the buyer's actual cash-to-close came in $1,190 higher than the first adjustment sheet showed -- fully explained once Quebec's no-deposit rule was applied correctly instead of an assumption borrowed from another province's practice.

31.5% TDS sits comfortably inside CMHC's 44% maximum on this insured purchase -- the deposit correction never touched the ratios at all.

What to take from this file

  • 01Quebec's Civil Code bars a landlord from ever collecting a security deposit or advance rent for a dwelling. Most other provinces allow some version of a last-month's-rent deposit; Quebec does not.
  • 02A last month's rent credit on a statement of adjustments is a routine assumption borrowed from common-law practice. Confirm it actually applies before relying on it in Quebec.
  • 03When the fund a credit assumes doesn't legally exist, remove the credit entirely. Don't renegotiate it to a smaller figure -- there is nothing there to split.
  • 04Confirm cash-to-close corrections with the buyer well before closing. A documented correction lands very differently than a surprise at the notary's office.
  • 05A deposit-credit correction and the mortgage ratios are two separate questions. This file's TDS was never affected by either version of the adjustment sheet.
