Subletting 101: What is it and how does it work?

By: Aya Alhakim on April 7, 2026

Key takeaways:

Subletting allows you to temporarily rent out your home or apartment while keeping your lease, but you remain responsible for rental payments, damages, and lease compliance.
In Canada, subletting requires your landlord’s written consent; subletting without permission can lead to eviction or legal penalties.
A clear sublease agreement and proper screening of subtenants can help reduce legal, financial, and trust-related risks.
Home insurance is an important consideration—your tenant policy may not cover a subletter, so increased liability coverage or separate renter’s insurance may be needed.

Planning to leave your rental space for a month—or even a year—but don’t want to give up your home or apartment? Subletting can make that possible. Done right, it lets you keep your lease, cover your rent, and return home when you’re ready. Done wrong, it can put your housing at risk.

Whether you’re studying abroad, starting a job in another city, or taking a long break, subletting has legal and financial responsibilities that many renters don’t fully understand. Before you hand over your keys, here’s what you need to know.

What is subletting?

Subletting is when you rent out your place to someone else for a while. You stay responsible for paying rent and taking care of the property, even though someone else—the subtenant or subletter—lives there.

This is known as a complete sublet and requires the landlord’s permission. It can benefit both parties: you cover your rental costs while away, and the subtenant gets a furnished home without signing a new lease.

Other options include partial sublets, where you rent out part of the property while still living there, and roommate sublets, where you rent out a room or shared space.

All arrangements require the landlord’s written consent, and the main tenant remains responsible for the entire lease and property.

Is it a good idea to sublet?

Complete subletting has its pros and cons. Knowing both can help you decide.

Pros of subletting

Save money: Subletting can help cover rent and utilities while you’re away.
Keep your lease: Avoid breaking your lease and return more easily later.
Flexibility: Travel without needing to look for a new home on return.

Cons of subletting

Responsibility: You’re liable for unpaid rent or damages caused by a subletter.
Trust: Finding a reliable subletter can be difficult.
Legal risk: Lease restrictions or missing written permission can cause problems.

Are you legally allowed to sublet?

Start with your lease. Some contracts prohibit subletting; others allow it with conditions, such as rent limits or time restrictions.

If you’re unsure, ask your landlord or property manager.

Landlords may require a formal sublease agreement outlining notice periods, guest rules, rent amounts, and payment dates. Having everything in writing helps prevent disputes.

Is it legal to sublease or sublet my rental space without telling my landlord?

In Canada, subletting without your landlord’s knowledge is illegal. In Ontario, landlords must give consent unless they have a valid reason to refuse.

Subletting without permission can lead to eviction for both you and your subtenant.

What kind of insurance coverage is better for subletting?

Subletting introduces new risks. Most tenant insurance policies don’t cover a subletter’s belongings.

Consider increasing liability coverage to protect against accidents while you're away.

You can also encourage your subletter to get their own renter’s insurance .

Frequently asked questions about subletting your rental home or apartment in Canada

How do you set a fair sublet price?

When subletting a home or apartment, many renters offer a discount, particularly in slower or less competitive rental markets. Charging 70–80% of your regular rent is common in Canada, though some tenants are able to charge the full amount depending on location, demand, and whether the unit is furnished.

To set a fair sublet price, compare similar listings in your area and consider whether utilities, internet, or parking are included. Transparent pricing can help attract reliable subletters and reduce disputes.

Where can you find a trustworthy subletter?

Finding a reliable subletter often starts within your existing network. Begin by asking friends, family, or colleagues, then expand to community or alumni groups or check with your landlord or leasing office.

Online platforms such as Craigslist or Kijiji can also be effective, but careful screening is essential. Interview candidates, check references, and confirm employment or school details before finalizing a sublet.

Are you still responsible for rent and damages when you sublet?

Yes. If you sublet your home or apartment, you remain legally responsible for paying rent and ensuring the unit is not damaged. Even though a subtenant occupies the space, the original tenant remains accountable to the landlord.

If a subletter fails to pay rent or causes damage, the landlord can pursue the leaseholder for payment or repairs. This is why thorough screening and clear sublease agreements matter.

Do you need a sublease agreement and tenant insurance when subletting?

Although not always legally required, a written sublease agreement is strongly recommended. It should clearly outline rent, payment deadlines, sublet length, guest rules, and notice requirements.

Insurance is also an important consideration. Most tenant insurance policies do not cover a subletter’s belongings, and liability coverage may be limited.
