Data sources and methodology

Target population

The target population includes enterprises in Canada that provide residential mortgages.
These enterprises were selected from the following North American Industry Classification System (NAICS) codes:

- 5221: Depository credit intermediation
- 5222: Non-depository credit intermediation
- 5223: Activities related to credit intermediation
- 523: Securities, commodity contracts, and other financial investments and related activities
- 524: Insurance carriers and related activities
- 5269: Other funds and financial vehicles.

The observed population includes the largest enterprises by assets selected among the enterprises whose contribution makes up more than 95% of the corresponding NAICS code. It also includes units found using a pilot study, a filtering pre-contact phase and lists from the Canada Mortgage and Housing Corporation (CMHC).

Instrument design

The Survey of Non-Bank Mortgage Lenders was designed in consultation with CMHC. Consultations and questionnaire testing took place across Canada with key industry players. Questionnaire design specialists reviewed the survey questionnaires. Their comments on the design and content were incorporated into the final versions.

Error detection

Edits are applied at the micro level. The data are subjected to a detailed quality review process with checks to detect missing, invalid or inconsistent entries or to identify records that are potentially erroneous. Inconsistent or invalid information is also reviewed at the analysis stage. This includes a comparative analysis to other sources of related data and information, where available.


After edits are applied, two classes of units are created: partial non-response cases and total non-response cases. For the units for which partial data have been collected, these partial data are used with auxiliary information to impute the missing data for the unit. Units which do not respond in the current period are fully imputed. For those units for which historical data exist, the historical data, taken in conjunction with current economic trend, are used to predict the current-period data. Otherwise Imputation makes use of information of similar units. Similar units are identified based on their industry classification as well as their value of assets.


Estimates are derived from the simple tabulation of data from the current population.

Quality evaluation

The survey results are analyzed before publication. In general, the analysis includes a detailed review of the individual responses, a review of general economic conditions as well as historic trends and comparisons with other data sources. In addition, subject matter experts from outside Statistics Canada were given an opportunity to review the survey microdata and estimates, as well as provide feedback on their quality prior to their official release. A particular investigation is done on the units considered as out of scope for the study.

Disclosure control

Statistics Canada is prohibited by law from releasing any information it collects which could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data.

Revisions and seasonal adjustment

No seasonal adjustment or revisions to previously released data is considered.

Data accuracy

A census was taken from the observed population. These were found using a pilot study, a filtering pre-contact phase and lists provided by CMHC. Data are collected from every potential residential mortgage lender from the observed population.

The survey response rate was calculated as the number of respondents divided by the number of estimated in-scope units. The number of in-scope units includes all respondents and an estimate of the number of in-scope units included among non-respondents. The overall response rate for the survey is 70.2%
