Waste Management Industry Survey: Government Sector
Detailed information for 2016
Every 2 years
The survey provides information on waste management financial and employment characteristics. It also collects information on collection, disposal and recycling quantities reported by municipalities and other public bodies that provide waste management services.
Data release - June 15, 2018
The survey provides businesses, local governments, Environment Canada and various other public and private clients with comprehensive and comparable information on waste management financial and employment characteristics. It also collects information on collection, disposal and recycling quantities reported by municipalities and other public bodies that provide waste management services.
The data are also needed for the Environmental Accounting statistics of the System of National Accounts.
Waste and recycling quantity data are combined with parallel data from the Waste Management Industry Survey: Business Sector (record no. 2009).
Reference period: Calendar year
Collection period: Spring and summer following the reference year
- Pollution and waste
Data sources and methodology
The target population for this survey of waste management practices includes all large municipalities (population of 5,000 or more), or waste management commissions or boards representing municipalities.
The majority of the questions remain unchanged from cycle to cycle.
This survey is a census with a cross-sectional design.
Data are collected for all units of the target population, therefore no sampling is done.
Data collection for this reference period: 2017-04-17 to 2017-09-11
Responding to this survey is mandatory.
Data are collected directly from survey respondents.
Data are collected directly from survey respondents and derived from other Statistics Canada surveys.
Data are collected through a mail-out/mail-back process. A letter explaining the purpose of the survey, the requested return date and the legal requirements of response are included with the mail-out package. Follow-up procedures are applied when a questionnaire has not been received after a pre-specified period of time.
Note that the questionnaire is available in both English and French versions.

Many factors affect the accuracy of data produced in a survey. For example, respondents may have made errors in interpreting questions, answers may have been incorrectly entered on the questionnaires, and errors may have been introduced during the data capture or tabulation process. Every effort was made to reduce the occurrence of such errors in the survey. These efforts included: a complete verification of keyed data, validity and consistency edits, extensive follow-up with the large businesses, and consultation with selected government departments and industry associations.
Although most local governments were co-operative in answering the survey, some could not provide all the data required in the form in which it was requested. In cases where values were missing from survey cells or where the respondent did not complete a questionnaire even after extensive follow-up, information was imputed.
Employment and financial data for small municipalities that were not surveyed, as well as in-scope firms that did not respond, was imputed. Administrative sources such as the Statistics Canada Business Register and tax records were used to fill in the missing values.
This methodology type does not apply to this statistical program.
One way to assess data accuracy is to compare it with data from other sources. For example, if the survey data indicates that the amount of waste disposed and diverted has risen substantially since the previous survey, one might also expect operating revenues and expenses to have risen. Similarly, if a provincial report is released indicating that the amount of diverted materials has increased significantly in that province, one might expect the data obtained from these surveys to follow the same trend. If the data did not follow the expected trends it was investigated rigorously. Recycling estimates were compared and validated with those published by the provincial governments of Nova Scotia and Ontario.
In addition to these comparisons, data are compared to those published by other organizations such as provincial governments and cities. If there are significant differences between the different sets of comparable data, these must be accounted for and explained. This also applies to cases where there are large positive or negative changes in the data values from cycle to cycle.
Statistics Canada is prohibited by law from releasing any data which would divulge information obtained under the Statistics Act that relates to any identifiable person, business or organization without the prior knowledge or the consent in writing of that person, business or organization. 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.
An intensive peer review of all tabular data is conducted prior to publication. This manual verification ensures that both inter and intra tabular comparisons cannot be made that may lead to disclosure of confidential data.
Revisions and seasonal adjustment
Revisions are made for the previous survey reference period, with the initial release of the current data, as required. The purpose is to address any significant issues with the data that were found between survey cycles. The actual period of revision depends on the nature of the issue, but rarely exceeds three years. For the most current data please refer to CANSIM tables 153-0041 to 153-0045.
The accuracy of data collected in a census survey is affected by non-sampling error. Examples of non-sampling error include coverage error, data response error, non-response error, and processing errors. Every effort is made to reduce these types of errors including verification of keyed data, consistency and validity edits, extensive follow up and consultation with government departments and industry associations.
