Employees of Canada. Dept. of Public Printing and Stationery

Canada's Civil Service List is a fabulous resources for finding public servants. Depending on the date you'll find birthdate, religion, salary and employment details. But it ceased being published just after the Great War.
If you're interested in a later period, and the person of interest was an employee of the Canada Dept. of Public Printing and Stationery, Canadiana.ca has 16 issues of an employee directory, for 1922, 1924-1932, 1935-1940 which gives name, section and address.

A reminder that next Wednesday 24 May 24, 2017 at 6:30pm at the Main Branch of the Ottawa Public Library there will be a presentation by Daniel Velarde, Canadiana.org Communications Officer, on Early Canadiana Online, a virtual library of full-text historical content about Canada, including books, magazines and government documents from the 16th to the early 20th century.   See https://biblioottawalibrary.ca/en/event/early-canadiana-online
