Rental property · Conversion
Not an owner's decision. An authorization from the Tribunal, and a race against deadlines.
Authorization is mandatory
The Tribunal: "any person who wishes to convert one or more properties to divided co-ownership must apply for authorization from the Tribunal administratif du logement if the property has at least one dwelling or has had at least one dwelling in the last 10 years." Under the law, a dwelling means premises rented for residential purposes, offered for rent, or vacant after having been rented.
The notice of intent, and its immediate effect
Before any other step, the owner gives each tenant written notice of the intent to convert, with a copy to the Tribunal. The effect is immediate and decisive: once that notice is given, tenants gain an unlimited right to maintain occupancy, and barring rare exceptions or their consent, cannot be displaced by a repossession exercised by an eventual purchaser.
The municipal step
- Montreal agglomeration: conversion is prohibited. Where the municipality has adopted a by-law allowing exemptions, a resolution of the municipal council granting that exemption is required.
- Elsewhere in Quebec: either a resolution of the municipal council authorizing the conversion, or a certificate attesting that the planned conversion complies with municipal by-laws, or that no by-law restricting conversion is in effect.
The deadlines
- Six months to submit the application to the Tribunal, running from the notice of intent or the municipal document, whichever comes later.
- 45 days after the application is introduced to file proof of notification and the list of exhibits.
- 10 days after the poster goes up in front of the building for anyone to make written representations.
- One year after authorization to register the declaration of co-ownership in the Land Registry. "Once this period has elapsed, the authorization becomes null and void", unless an extension is applied for before it expires.
The sanction
"Any interested party, including the Tribunal administratif du logement, may ask the Superior Court to have any declaration of co-ownership that has been registered without the Tribunal's authorization removed, when such authorization is required, and to have any contract arising from this registration cancelled."
In other words, a botched conversion can unwind the sales that followed it.
Where this actually lands: at purchase, not after
These rules have one thing in common. They are not discovered while managing a building, they are discovered while buying one. A lease carrying a void clause, a deposit that was never lawful, a dwelling occupied by a succession, a subdivision project the law has suspended: each of those is sold along with the building.
That is why we read the leases, the building's tax position and the history of notices before making an offer on a plex, never after acceptance.
Three habits before buying a rental property
- Ask for every lease and its schedules, not just the rent roll. The clauses hide in the schedules.
- Have the tax modelled before the offer, including the seller's CCA position and what you intend to do with your own.
- Check what the law still permits for your plan. Repossession, eviction and conversion rules have changed and keep changing.
