Sharing an apartment is one of the most effective ways to lower your housing costs in Quebec — but the way your lease is structured determines how much risk you take on. The single most important question isn’t who does the dishes; it’s whether you’re all on one joint lease or each on your own. That choice quietly decides what happens if a roommate stops paying or moves out.
In 2026, with rents climbing across Quebec City, more people are choosing to share — students, young professionals, and newcomers alike. Co-living can mean a bigger, better-located apartment for far less per person. At Frederic Murray Rentals, we want tenants to enjoy those savings without nasty surprises. Here’s how shared renting actually works.
Why renting with roommates makes sense in 2026
The appeal of roommates comes down to simple math: split the rent, and your housing budget stretches much further. In a tight, expensive market, that advantage is hard to ignore.
Sharing an apartment offers several benefits:
- Lower costs, as rent and utilities are divided among roommates.
- A better apartment, since pooling budgets unlocks larger or nicer units.
- Shared responsibilities, from chores to errands.
- Companionship, which many renters value, especially newcomers.
These advantages are real, but they come bundled with shared legal obligations. Understanding those obligations before you sign is what keeps the savings from turning into stress. It also helps to know your full budget first, which our tenant’s budgeting guide to the true cost of renting lays out.
One lease or separate leases? The crucial distinction
Before anything else, find out how the lease is structured — it changes everything about your responsibilities. There are two main arrangements, and they protect you very differently.
The two structures are:
- A single joint lease, where all roommates are co-tenants on the same lease together.
- Separate leases, where each roommate has their own individual lease with the landlord.
With a joint lease, you and your roommates share responsibility for the whole apartment. With separate leases, you’re generally responsible only for your own. Separate leases offer more protection but are less common; most shared apartments use a single joint lease — which makes understanding joint liability essential.

Understanding solidary (joint) liability
This is the part every roommate needs to understand: on a joint lease, you may be responsible not just for your share, but potentially for the entire rent. This concept — often called solidary liability — is where shared renting carries real risk.
In practical terms, on a joint lease with solidary liability:
- If one roommate doesn’t pay, the landlord can pursue the others for the full rent.
- Your responsibility isn’t limited to “your portion” of the rent.
- One roommate’s actions can affect everyone, financially and legally.
Many leases include a solidarity clause that makes this explicit, so always read the lease carefully before signing. Plain-language explanations of how co-tenancy and solidary liability work are available through Éducaloi. Knowing this upfront is exactly why choosing trustworthy roommates matters so much.
What happens when a roommate moves out
Here’s a common and costly misunderstanding: a roommate can’t simply walk away from a joint lease. Moving out physically doesn’t end someone’s legal obligations under the lease.
When a roommate wants to leave a joint lease:
- The lease doesn’t automatically end or release them.
- They typically need to assign their share, with the landlord’s consent, or arrange a replacement.
- Without proper steps, a departing roommate may remain liable for rent.
This means a roommate who leaves without following the correct process can still be on the hook — and so can those who stay. Handling a departure properly, rather than informally, protects everyone. It’s worth agreeing in advance how you’ll deal with someone leaving before it ever happens.

Splitting rent, utilities, and responsibilities
Money is the most common source of roommate conflict, so settle it clearly from day one. A little structure prevents a lot of tension later.
Smart roommates agree, in writing, on:
- How rent is split and who pays the landlord.
- Whose name is on the utility accounts and how those bills are divided.
- Shared expenses like internet, and how they’re tracked.
- Household responsibilities, from cleaning to supplies.
A written roommate agreement — separate from your lease with the landlord — is one of the best tools for a smooth arrangement. It doesn’t change your obligations to the landlord, but it keeps roommates accountable to each other. And remember: in Quebec, a landlord can’t demand a security deposit, so your shared move-in costs are essentially the first month’s rent, not a deposit.
Choosing the right roommates
Because a joint lease ties your finances to your roommates, choosing them well is a financial decision, not just a social one. The wrong roommate can cost you money; the right one makes co-living genuinely enjoyable.
When evaluating potential roommates, consider:
- Financial reliability, since their ability to pay affects you directly.
- Compatibility, including lifestyle, schedules, and habits.
- Communication style, because problems get solved by people who talk openly.
- Shared expectations, on guests, noise, cleanliness, and quiet hours.
It’s worth treating roommate selection a bit like a mini-application: have honest conversations about money and lifestyle before committing. A few candid questions upfront save months of friction later.
Tips for a smooth co-living arrangement
Once you’ve chosen well and signed wisely, good habits keep the household running smoothly. Most roommate disputes are preventable with a little structure and respect.
To make shared living work:
- Put key agreements in writing, especially around money and moving out.
- Communicate early and openly when issues arise.
- Respect shared and private spaces, honouring everyone’s peaceful enjoyment.
- Revisit the arrangement periodically as circumstances change.
