Statistics Canada has an established practice of revising the Labour Force Survey (LFS) estimates after a new series of postcensal population estimates become available. This standard revision includes: an update of the LFS estimates to reflect the most recent series of postcensal population estimates; updates to more current industry and occupation classifications; an update of geographic boundaries; as well as an update of seasonal adjustment. These revised LFS estimates are now available.

Up to December 2010, labour force estimates had been based on population data from the 2001 Census. Starting with today's release, all estimates are now based on the 2006 Census population counts. With this revision, the total Canadian population has been revised downward 0.3%, which is approximately half the size of the previous revision in 2005.

Levels of employment and unemployment have been revised downward when using the new population estimates. For December 2010, overall employment was revised down 0.6%, mostly the result of a downward revision of the population aged 25 to 54, the group with the highest employment rate. However, the unemployment rate was unchanged for December 2010.


Compared with the employment peak of October 2008, employment in December 2010 was lower by 30,000 (-0.2%) based on the revised LFS estimates.

Between the employment peak of October 2008 and the recent low in July 2009, the revised LFS estimates show an employment decline of 428,000 (-2.5%). Between July 2009 and December 2010, the revised LFS estimates indicate employment increased by 398,000 (+2.4%).

For the provinces, employment levels in December 2010 were revised downward by 1% or more for New Brunswick (-2.4%); British Columbia (-1.9%); Newfoundland and Labrador (-1.8%) and Prince Edward Island (-1.1%). The only upward revision was in Alberta (+0.8%).
