Canada Mortgage and Housing Corporation (CMHC) conduct the Rental Market Survey(RMS) every year in October to estimate the relative strengths in the rental market. The survey is conducted on a sample basis in all urban areas with populations of 10,000 and more. The survey targets only privately initiated structures with at least three rental units, which have been on the market for at least three months. The survey collects market rent levels, availability, turnover and vacancy unit data for all sampled structures.

The survey is conducted by a combination of telephone interviews and site visits, and information is obtained from the owner, manager, or building superintendent. The survey is conducted during the first two weeks of October, and the results reflect market conditions at that time.

CMHC is constantly reviewing the Universe of rental structures in the rental market Universe to ensure that it is as complete as possible. Every year, any newly completed rental structures with at least 3 rental units are added to the Universe. In addition to this, CMHC undertakes comprehensive reviews by comparing the Universe listing to other sources of data to ensure that the list of structures is as complete as possible.

CMHC’s Rental Market Survey provides a snapshot of vacancy, availability, and turnover rates and average rents in both new and existing structures. In October 2006, CMHC introduced a new measure for the change in rent that is calculated based on existing structures only. This estimate is based on structures that were common to the survey sample for the previous and the current Rental Market Surveys. The change in rent in existing structures is an estimate of the change in rent that the landlords charge and removes compositional effects on the rent level movement due to new buildings, conversions, and survey sample rotation. The estimate of percent change in rent is available in all Canada and Provincial Highlight reports, and also in the CMA reports. The rent levels in new and existing structures are also published. While CMHC publishes only those percent change in rents in existing structures which are statistically significant, changes in rents that one might calculate based on rent levels in new and existing structures may or may not be statistically significant.

A letter code representing the statistical reliability (i.e., the coefficient of variation (CV)) for each estimate is provided to indicate the data reliability. CV of an estimate is defined as the ratio of the standard deviation to the estimate and CV is generally expressed a percentage. For example, let the average rent for one bedroom apartments in a given CMA be and its standard deviation be . Then the Coefficient of Variation is given by.

METHODOLOGY FOR CONDOMINIUM APARTMENT SURVEY

Canada Mortgage and Housing Corporation (CMHC) conducts the Condominium Apartment Survey (CAS) in late summer and early fall to estimate the relative strengths in the condo apartment rental market The CAS collects the number of units being rented out and the vacancy and rent levels of these units in the following CMAs: Calgary, Edmonton, Gatineau, Halifax, Hamilton, Kelowna, Kitchener, London, Montréal, Ottawa, Québec, Regina, Saskatoon, Toronto, Vancouver, Victoria and Winnipeg. The CAS is conducted by telephone interviews and information is obtained from the property management company, condominium (strata) board, or building superintendent. If necessary, this data can be supplemented by site visits if no telephone contact is made.

CMHC publishes the number of units rented, vacancy rates and average rents from the Condominium Apartment Survey. A letter code representing the statistical reliability (i.e., the coefficient of variation (CV)) for each estimate is provided to indicate the data reliability. 

RENTAL MARKET SURVEY (RMS) AND CONDOMINIUM APARTMENT SURVEY (CAS) DATA RELIABILITY

CMHC does not publish an estimate (e.g. Vacancy Rates and Average Rents) if the reliability of the estimate is too low or the confidentiality rules are violated. The ability to publish an estimate is generally determined by its statistical reliability, which is measured using the coefficient of variation (CV).

Reliability codes for proportions

CMHC uses CV, sampling fraction and universe size to determine the ability to publish proportions such as vacancy rates, availability rates and turnover rates. The following letter codes are used to indicate the level of reliability of proportions:

A — Excellent
B — Very good
C — Good
D — Fair (Use with Caution)
** — Poor — Suppressed

The following two tables indicate the level of reliability of proportions:

If the proportion is Zero (0) and sampling fraction is less than 100% then the following levels are assigned:

  Sampling Fraction (%) range
Structures in Universe (0,20]* (20,40] (40,60] (60,80] (80,100)
3 – 10 Poor Poor Poor Poor Poor
11 – 20 Poor Fair Fair Fair Good
21 – 40 Poor Fair Fair Good Very Good
41 – 80 Poor Fair Good Good Very Good
81+ Poor Good Good Very Good Very Good

*(0, 20] means sampling fraction is greater than 0% but less than or equal to 20%; others are similar

Otherwise, the following table is used to determine the reliability level of proportions:

  Coefficient of Variation (CV) %
Vacancy Rate 0 (0,5] (5,10] (10,16.5] (16.5,33.3] (33.3,50] 50+
(0,0.75] Excellent Excellent Excellent Excellent Excellent V. Good V. Good
(0.75,1.5] Excellent Excellent Excellent Excellent Excellent Fair Poor
(1.5,3] Excellent Excellent Excellent V. Good Good Poor Poor
(3,6] Excellent Excellent V. Good Good Fair Poor Poor
(6,10] Excellent Excellent V. Good Good Poor Poor Poor
(10,15] Excellent Excellent Good Fair Poor Poor Poor
(15,30] Excellent Excellent Fair Poor Poor Poor Poor
(30,100] Excellent Excellent Poor Poor Poor Poor Poor

Reliability codes for averages and totals

CMHC uses the CV to determine the reliability level of the estimates of average rents and a CV cut-off of 10% for publication of totals and averages. It is felt that this level of reliability best balances the need for high quality data and not publishing unreliable data. CMHC assigns a level of reliability as follows (CV’s are given in percentages):

A — If  the CV is greater than 0 and less than or equal to 2.5 then the level  of reliability is Excellent.
B — If the CV is greater than 2.5 and less than or equal to 5 then  the level of reliability is Very  Good.
C — If the CV is greater than 5 and less than or equal to 7.5 then  the level of reliability is Good.
D — If the CV is greater than 7.5 and less than or equal to 10 then  the level of reliability is Fair.
** — If the CV is greater than 10 then the level of reliability is Poor. (Do Not  Publish)

Definitions

Availability: A rental unit is considered available if the existing tenant has given, or has received, notice to move, and a new tenant has not signed a lease; or the unit is vacant (see definition of vacancy below).

Rent: The rent refers to the actual amount tenants pay for their unit. No adjustments are made for the inclusion or exclusion of amenities and services such as heat, hydro, parking, and hot water. For available and vacant units, the rent is the amount the owner is asking for the unit.

It should be noted that the average rents reported in this publication provide a sound indication of the amounts paid by unit size and geographical sector. Utilities such as heating, electricity and hot water may or may not be included in the rent.

Rental Apartment Structure: Any building containing three or more rental units, of which at least one unit is not ground oriented. Owner-occupied units are not included in the rental building unit count.

Rental Row (Townhouse) Structure: Any building containing three or more rental units, all of which are ground oriented with vertical divisions. Owner-occupied units are not included in the rental building unit count. These row units in some centres are commonly referred to as townhouses.

Vacancy: A unit is considered vacant if, at the time of the survey, it is physically unoccupied and available for immediate rental.

Turnover: A unit is counted as being turned over if it was occupied by a new tenant moved in during the past 12 months. A unit can be counted as being turned over more than once in a 12 month period.

Definitions of census areas referred to in CMHC publications are as follows:

A census metropolitan area (CMA) or a census agglomeration (CA) is formed by one or more adjacent municipalities centred on a large urban area (known as the urban core). The census population count of the urban core is at least 10,000 to form a census agglomeration and at least 50,000 to form a census metropolitan area. To be included in the CMA or CA, other adjacent municipalities must have a high degree of integration with the central urban area, as measured by commuting flows derived from census place of work data. CMAs and CAs contain whole municipalities or Census Subdivisions.

October 2016 data is based on Statistics Canada’s 2011 Census area definitions. October 2017 data is based on Statistics Canada’s 2016 Census area definitions.
