Monthly estimates of business openings and closures, January 2022

Today's release includes a new process for seasonally adjustment in the presence of the outliers generated by the response to COVID-19. The new process has a greater number of outliers that are explicitly recognized at the outset of the seasonal adjustment process. This leads to a greater number of outliers being taken into account than was previously occurring. Examinations of seasonally adjusted data using the new process show results that are more stable over time and produce smaller revisions. The implementation of the new process led to data revisions compared to last month's release.

Every new month of data leads to a revision of the previously released data due to such factors as the seasonal adjustment process and a new version of the Generic Survey Universe File (or vintage of the Business Register). As such, the estimates may vary compared with a previous release.

Openings are defined as businesses with employment in the current month and no employment in the previous month, while closures are defined as businesses that had employment in the previous month, but no employment in the current month. Continuing businesses are those that have employees in both months, and the active population in any given month is the number of opening and continuing businesses in that month. Reopening businesses are defined as opening businesses that were also active in a previous month (that is, they closed in a given month and had positive employment in a subsequent month). In contrast, entrants are opening businesses that were not active in a previous month.

The definition of exits is based on the Longitudinal Employment Analysis Program (LEAP) annual exits. Because the LEAP definition can require up to 24 months of data to be counted as an exit, projections of exits using predicted growth rates are implemented using a regression model of exits on closures of more than six months. As a result, there are no published exits in the last six months. A temporary business closure is the difference between closures and exits. For more information on temporary business closures and exits, see "Defining and measuring business exits using monthly data series on business openings and closures."

A business is defined as an enterprise operating in a particular geography and industry.

The vast majority of businesses operate in one industry and one location or geography. For these businesses, in the monthly estimates of openings and closures, they will be counted once at the national/provincial level. For example, a retailer in Windsor, Ontario, will be counted as an active business in the Ontario estimates and once in the national estimates.

Some businesses can have multiple operations, and these can be in different industries and geographies. For such businesses, in the monthly estimates of openings and closures, they can be counted more than once because they are active in multiple industries or geographies. For example, if a retailer has operations in both Alberta and Ontario, it will be counted as an active business in both provinces, but only once at the national level because it represents only one active firm. Similarly, a firm with retail and wholesale operations will be counted in both industries when individual industries are examined. However, when the business sector is examined, the firm counts only once because at that level it represents one firm active in the business sector.
