Symmetric input-output tables, 2021

Released: 2023-07-05

The national symmetric input-output tables for 2021 are now available. The national symmetric input-output tables for 2019 and 2020 have been revised.

The symmetric industry by industry input-output tables show inter-industry transactions, that is, all purchases of an industry from all other industries, as well as expenditures on imports and the components of value added, such as wages and gross operating surplus. Similarly, the symmetric final demand tables show all purchases by each final demand category from all industries, as well as expenditures on imports. The symmetric input-output tables are analytically derived from the industry by product supply and use tables.

  Note to readers

The estimates for 2020 and 2021 are only available nationally. They are based on advanced estimates of the Canadian supply and use tables that were modelled based on industry indicators of output and gross value added and benchmarked to published income and expenditure account figures.


The product Symmetric Input-Output Tables for 2021 (Catalogue number15-207-X) is now available upon request.
