Supply, Use and Input-Output Tables

Summary of changes

Activity on this program started: 1961

Reference period of change - 2009

The 2009 data reflect new input-output classifications, and conceptual and statistical improvements as part of a comprehensive revision to the System of national economic accounts. They are consistent with revisions incorporated in the Canadian economic accounts, published on October 1, 2012, and with the provincial and territorial economic accounts, published November 19, 2012.

Changes have not been incorporated to the national and provincial-territorial input-output tables for years prior to 2009.

Reference period of change - 2000

The Provincial Input-Output Accounts (PIOA) has incorporated several changes for the manufacturing industries. Theses changes originate from the Annual Survey of Manufactures (ASM) that was redesigned for reference year 2000.

As well, beginning in reference year 2000, the PIOA includes estimates of head office activity as measured by the Annual Survey of Head Offices and Other Business Support Units.

Reference period of change - 1997

For a brief history of the program before 1997, refer to the document "Evolution of the Canadian Input-Output Tables, 1961 to Date" in the Documentation on the survey description page.

Beginning with reference year 1997, Statistics Canada is providing input-output (IO) accounts for all provinces and territories of Canada on an annual basis. In the past, annual publication of input-output accounts was limited to the national economy.

As well, beginning with the 1997 reference year, the input-output tables industries are classified by the North American Industry Classification System (NAICS) rather than the 1980 Standard Industrial Classification (SIC), to be consistent with Statistics Canada's adoption of NAICS. This has led to changes in the detail and presentation of goods and services.

The valuation of industry gross domestic product has changed from factor cost to basic price, in accordance with conventions recommended by the united nation report, System of National Accounts, 1993. Under the old valuation, industry gross domestic product was calculated to include the returns to labour and capital only, excluding taxes or production subsidies. The new valuation of industry GDP is basic prices which includes Other Taxes on Production and Other Subsidies on Production. Data on gross output is at modified basic price, because production data show prices actually received by producers thus reflecting the effect of subsidies on products.
