Mr. Speaker, with regard to (a), the Treasury Board Secretariat, TBS, uses data from the regional pay system to track employment numbers for the federal public service, in particular those departments and agencies named in schedules I, IV and V of the Financial Administration Act.
Data on employees and payroll for the Canadian Forces, CF; the Royal Canadian Mounted Police, RCMP; and crown corporations is maintained by each organization.
With regard to (b), there are several reports published throughout the year that contain employment statistics for the core public administration and/or federal public service. These include the annual report to Parliament on employment equity in the public service, the annual report to Parliament on official languages, and the Clerk of the Privy Council's annual report to the Prime Minister on the public service.
Also, there are several factsheets published on the Treasury Board Secretariat website, http://www.tbs-sct.gc.ca/res/stats/hrs-srh-eng.asp, that contain the latest statistical information on the federal public service work force. These factsheets are reported as of March of each year and are updated annually.
Aggregate payroll and employment data for the Canadian Forces up to March 2012 is available publicly through Statistics Canada.
With regard to (c), while some statistical information can be generated at other times, reports are usually generated as of March of each year to ensure consistency and comparability.
With regard to (d), yes, employment statistics are available from the TBS on tenure, including indeterminate, term, casual, or student; work schedule, including part-time or full-time; province and city; gender and age, et cetera. TBS compiles these statistics and some are available on the TBS website.
As contractors are not considered government employees, TBS does not collect data on them.
The CF and RCMP data are not available by tenure. The data does distinguish between types. For the CF, it distinguishes between reservists and regular force. For the RCMP, it distinguishes between civilian members and regular members. The RCMP data is also available by province and gender.
