Amenity density

Definition: Amenity density is an accessibility measure based on population-weight distance to neighbouring services and amenities. It is a composite measure calculated in the Proximity Measures Database through a collaboration between Statistics Canada and Canadian Mortgage and Housing Corporation. The amenity density measure considers access to a grocery store, pharmacy, and public transit stop within 1 km walking; a childcare facility, primary school, and library within 1.5 km walking; a health facility within 3 km driving; and employment within 10 km driving, and assigns each dissemination block a value of low, medium, and high. A dissemination block is considered to have low amenity density if it does not have access to all of those services in the specified radius. Medium and high density neighbourhoods are those with access to all the eight services in the selected radius, with high density being those areas with proximity to each of the eight services in the top third of the distribution of all proximity values across Canada.

Core housing need

Definition: According to Statistics Canada, a household is in core housing need if its housing falls below at least one of the adequacy, affordability, or suitability standards and if it would have to spend 30% or more of its total before-tax income to pay the median rent of alternative local housing that is acceptable (meets all three housing standards). Not all households are assessed for core housing need. The exclusion criteria are documented in Statistics Canada’s detailed definition for core housing need

Estimated percentage of affordable private market rental units

Definition: “Estimated percentage of affordable private market rental units” refers to the proportion of units where the asking rate in the last five years was either at or below a rental affordability definition that we have created for this project.

We created our own rental affordability definition because there is no standardized measure in Canada and those that do exist are more commonly tied to real estate market trends (e.g. percentage of average market rent) rather than income trends.

Our rental affordability definition considers the units that are financially accessible to renters by economic family size based on their income. We have also chosen to focus on economic families instead of households. Statistics Canada defines an economic family as a group of people who live together and are related to each other by blood, marriage, common-law union, adoption or a foster relationship. While many households are comprised of economic families, they can also include roommates who may only be living together for financial reasons and are otherwise unlikely to stay together as a unit.

It is commonly accepted that shelter is considered affordable if it costs less than 30% of gross monthly income. We applied 30% to the median before-tax income of economic families that were renting and additionally filtered out economic families that paid no rent and that were receiving government subsidies. The median income was calculated for each region independently to account for geographic variation in income. Therefore, for example, our rental affordability definition procures a different maximum affordable shelter cost for a two-person family in Toronto and a two-person family in Halifax.

Because the income of one-person households is quite different from two-person families and because families of different sizes occupy different sized units, our rental affordability definition produces a different maximum affordable shelter cost for each family size. In other words, our rental affordability definition asks, for example, what is the maximum shelter cost that is affordable for a one-person household and what size units are suitable for that household? We repeat this question for each family size. This contrasts with other affordability measures that set a single shelter cost threshold regardless of the family size.

We chose median income based on a historical analysis of the buying power of renter economic families. The median has traditionally marked a turning point where renter economic families no longer have disproportionate access to the rental market relative to their income. For example, a family in the 25th percentile income, may only have the purchasing power to access 10% of the rental units available on the market. History has shown that families in the median (or 50th percentile) income tend to reach parity and can afford approximately 50% of the rental units available on the market.

To match family sizes to units, we applied an occupancy standard of a maximum of one bedroom for every person and a minimum of one bedroom less than the maximum. Therefore, for each family size, there is one maximum affordable shelter cost applied to two different unit sizes. For example, for a two-person family, 1-bedroom and 2-bedroom units meet our occupancy standard and we count the number of units for both that are under the maximum affordable shelter cost (30% of median income of two-person renter economic families).

In a competitive rental market, the average market rent typically lags behind current asking prices for rent. This is because sitting tenants benefit from rent control which limits annual increases. Since we are interested in the asking prices of units, we can exclude units with long-standing sitting tenants by looking at households that recently moved. While the Census allows us to identify households that moved in the last year, in our rental affordability definition we have used households that moved in the last five years in order to increase the sample size.

Estimated percentage of affordable primary market rental units (sitting and new tenancies)

Definition: The “estimated percentage of affordable primary market rental units (sitting and new tenancies)” is akin to the definition for the “estimated percentage of affordable private market rental units” except in two important ways. In the former, only primary market units are counted and average market rent is used instead of the asking rate over the last five years. Therefore, compared to the estimated percentage of affordable private market units, this measure shows a higher proportion of affordable units because it includes longstanding tenants who have benefited from rent control. Due to this critical difference, it is not possible to make conclusions about the affordability of the primary market versus the broader private rental market based on these measures alone.

Primary market units are defined as private dwellings for rent in buildings constructed with the intention to supply the rental market. These units are owned, operated, and assigned by a landlord or private management company for profit. CMHC’s Rental Market Survey includes buildings with 3 or more rental units. For more details on CMHC’s definition for primary market units, visit their Methodology for Rental Market Survey page.

Eviction filings

Definition: The regional change in count of eviction filings from the previous year is shown for each geographic area and is expressed as a percentage. Areas with fewer than 30 filings within a given year are suppressed for data reliability purposes. Filings available through LEMR include all Landlord Applications for Termination of Tenancy and Unpaid Rent. These counts do not include tenants who are evicted illegally or choose to move before a formal legal process is initiated. The data provided through FOIP (Freedom of Information and Protection of Privacy) Operations contained only partial location information, rendering it impossible to display data on a level more granular than the municipality. Additional details regarding Applications for Termination of Tenancy and Unpaid Rent can be found on Alberta’s Residential Tenancies website

Forward Sortation Area

Definition: Forward Sortation Areas are geographic representations of the areas covered by the first three characters of a postal code. Since full six-character postal codes cannot be represented as geographic areas (they define linear postal carrier routes) and because postal codes are self-reported on the census, Forward Sortation Area boundaries can be highly irregular and they can be variable from census year to census year. A detailed explanation for how Statistics Canada constructs Forward Sortation Area boundaries can be found here.

Municipality

Definition: A municipality is a geographic area representing a local government as determined by provincial legislation. Where provinces have upper tier and lower tier municipalities, the lower tier municipalities are shown.

Non-market units

Definition: Non-market units are displayed as a percentage of the total rental market in each geographical area. The measure is established by dividing the number of non-market units by the total rental units per region which is estimated by dividing the number of renter households reported in the Census by the vacancy rate (also estimated through the CMHC Rental Market Survey).

Non-market units are private dwellings for rent in properties where rents are subsidized below market rates. Examples include social or public housing, supportive housing with self-contained units, rent-geared-to-income units, and other units with subsidies tied to the unit.

The count of non-market units is dependent on availability of municipal administrative data, and therefore this feature is only available in select areas. These include the city of Mississauga, City of Toronto, Durham Region, Halton Region, City of New Westminster, City of Vancouver, and Montréal agglomeration. Note that the Montréal agglomeration can only be displayed at the municipal level due to the nature of the available municipal administrative data. Most of these sources only provide current non-market inventory, therefore historic estimates of percentage of non-market units uses the assumption that non-market unit counts have not changed significantly.

Primary market units

Definition: Primary market units are displayed as a percentage of the total rental market in each geographical area. Here, primary market units are included regardless of affordability status. The measure is established by dividing the number of primary market units estimated through the CMHC Rental Market Survey by the total number of rental units. The total number of units is estimated by dividing the number of renter households reported in the Census by the vacancy rate (also estimated through the CMHC Rental Market Survey).

Primary market vacancy rate

Definition: Estimated percentage of all available primary market rental units that are vacant or unoccupied. This measure comes from the Canada Mortgage and Housing Corporation’s (CMHC) Rental Market Survey. CMHC counts a unit as vacant if it is physically unoccupied and available for immediate rental (at the time of the survey).

Rental Market Survey zone

Definition: Rental Market Survey zones are geographic areas that the Canada Mortgage and Housing Corporation uses to report results from its annual Rental Market Survey. These zones are geographically larger than census tracts and smaller than a municipality.

Rental units

Definition: The number of rental units in rental condominium buildings. Calgary’s property assessment data was used to determine this number, which did not provide unit count for other rental building types.

Secondary market condo units

Definition: Secondary market condo units are displayed as a percentage of the total rental market within a geographical area. The measure is established by dividing the number of rented condo units by the total number of rental units. The total number of rental units is estimated by dividing the number of renter households reported in the Census by the vacancy rate (also estimated through the CMHC Rental Market Survey).

Secondary market condo units are private dwellings for rent within a condominium development. A condominium is a residential complex with individually owned units and jointly owned common elements and land. It includes units purchased by individuals with the intention to operate rental units, rather than to occupy as residence. Condominium rentals are categorized as part of the “secondary market” units because they were built without the intention to supply the rental market, but are currently doing so.

Secondary market non-condo units

Definition: Secondary market non-condo units are displayed as a percentage of the total rental market in each geographical area. The measure is established by subtracting the number of primary market units, the number of secondary market condo units, and the number of non-market units from the estimated total rental units and dividing by the estimated total rental units. This measure can be calculated only when data from a minimum of three sources are available: Statistics Canada Census Profile, Canada Mortgage and Housing Corporation’s Rental Market Survey, and municipal administrative data. Therefore, this feature can only be provided in the follow areas: City of Mississauga, City of Toronto, Durham Region, Halton Region, City of New Westminster, City of Vancouver, and Montréal agglomeration. Note that the Montréal agglomeration can only be displayed at the municipal level due to the nature of the available municipal administrative data.

Secondary market non-condo units are private dwellings for rent that is not in a purpose-built rental apartment building or in a condominium. Secondary market non-condo units are typically basement or secondary suites, houses for rent, or units in small multi-unit dwellings. These rentals are categorized as part of the “secondary market” units because they were built without the intention to supply the rental market, but are currently doing so.

Share of regional change in primary market units

Definition: The regional share of change in primary market stock is calculated by dividing the change within a geographical area over the past year by the change within the larger region over the same period. If a particular area has a net year-to-year loss in its primary market stock, this will appear as a negative share in regional change of primary market units. Areas with less than 30 primary market units will be suppressed for data reliability purposes.
