Rental Increases 2021

22nd February 2021 Alex Clifford

No one wants to pay more rent. We are in the coldest part of the year  in Montreal, and it’s the time of year where tenants typically begin to receive notices of rental increase and lease modifications from their landlord. Each year, the percentage of average rental increases fluctuates, as they take into account all the rental components, which include taxes (municipal and school), insurance, and any renovations that were done in the building or in your apartment. As such, there is no fixed number for a fair rental increase, but you can use the Tribunal Administratif du Logement’s rent calculation tool for 2021 to determine what constitutes a reasonable rental increase for your dwelling.  

The following link contains the rent calculation tool for 2021, as well as information on the calculation tool: 

Though the notice indicates a rental increase, it is important to remember that it is a proposed modification. As a tenant, you have the legal right to refuse a rental increase or proposed modifications. When you first receive your notice of the rental increase, you must first make sure that your landlord has sent you a written notice in the right time frame that indicates the new rent on dollars, the proposed increase in dollars, or as a percentage of the current rent. Notices that are sent outside of this timeframe, or that do not contain this information, are not valid. The timeline for sending rental increases is as follows:  

Length of Lease 

Modification of lease Notice from Landlord 

1 year or more 

3 to 6 months before the end date of the lease 

Less than one year 

1 to 2 months before the end date of the lease 

No end date 

2 months before the start of the rental increase 

Lease of a room 

10 to 20 days before the end date of the lease 


If the notice of rental increase you received is valid and abides to these conditions, you then have four options:  

  1. Accept the proposed modifications and renew the lease 

  1. Refuse the proposed modifications and leave the dwelling 

  1. Refuse the proposed modifications and renew the lease 

  1. Refuse the proposed modifications, renew the lease, and offer to negotiate a lower rental increase 

The Tribunal Administratif du Logement’s webpage that is linked below contains more information on the specific rules that apply to rent increases for rental units (for example time periods allowed for serving notices, particular circumstances for members of a cooperative, or someone living in low-rental housing) are explained on the Tribunal’s website, which also provides a model of rent increase notice and a model reply to such a notice.
