Election Promise or Law in Force: What Applies to Your Quebec Transaction

Quebec votes today, October 5, 2026. During the campaign, commitments were made on housing and household taxation. For anyone buying or selling right now, a practical question arises: what actually applies to my transaction? The answer depends neither on the election result nor on any particular party: it depends on the path a promise has to take before it becomes a rule. The commitments themselves are covered in our article on home buyer promises in the 2026 Quebec election.

A promise is not yet a rule

An election promise is a political commitment. It says what a party intends to do if it forms the government. On its own, it creates no right, no obligation and no tax credit.

Between the commitment and the applicable measure, several things remain open: whether the measure will be adopted, in what form, with what conditions, and from when. Until those four questions have a written answer, the promise does not belong in a purchase or sale budget.

From platform to budget

Once formed, the government chooses which commitments it implements and in what order. For a tax measure or financial assistance, the usual step is the budget, or an economic update, which announces the measure, sets out its parameters and plans its funding.

At that stage, the measure has changed in nature: it is no longer a campaign promise but a decision announced by the government. Its parameters may still differ from what was promised, and the budget version is the one to read.

From budget to legislation or regulation

A tax measure becomes law when a bill is passed by the National Assembly and then assented to. Other measures go through a government regulation, published in the Gazette officielle du Québec, or through a program run by a ministry or agency, whose standards are published.

That final text sets the rules that actually apply: who is eligible, on what conditions, for what amount, and from when. It can be adopted months after the announcement, and its details can still differ from it.

The effective date: the one the text sets, sometimes the announcement

The text that implements a measure sets its effective date. It can come after adoption. It can also reach back in time: a tax measure announced in a budget can apply from the date of that announcement, even if the legislation is only passed later.

For a real estate transaction, the date that matters is the one the text uses: depending on the case, the date of the accepted promise to purchase, the deed of sale, registration in the land register, or another date. Two transactions signed the same day can therefore be treated differently depending on which step the text takes as its reference.

A transaction signed in October 2026

A promise to purchase accepted in October 2026 is calculated with the rules in force when it is signed. A measure promised during the campaign is not part of them, and nothing today tells us its final form or its effective date.

Three outcomes remain possible for a promised measure: it is never adopted; it is adopted and only applies to transactions after a future date; or it is adopted with an effective date reaching back to its announcement, and may then cover transactions already concluded. None of these outcomes can be predicted on election day.

What to check before building a measure into your numbers

• Has the measure been announced by the government, and not just promised during the campaign?
• Has the implementing text been adopted: assented legislation, published regulation or released program standards?
• What effective date does that text set, and which step of the transaction does it attach to?
• What eligibility conditions does it impose, and does the transaction meet them?

As long as any of these answers is missing, the prudent approach is to build financing and price on the rules in force, and to keep the documents that date each step of the transaction. If a measure is later adopted with retroactive effect, those documents are what will let you check whether it applies.
