One place where you won't find a new kid in the office block - Canada. It may have been barely noticeable two decades ago, but there's no denying the fact now that Canada's workforce is going grey.

Census data shows that the country's labor force is increasingly being made up of older workers. Recent labor statistics found the new median age of Canada's workforce is over 41-years-old, and revealed that more than two million Canadians aged 55 to 64 are still gainfully employed.

In 2006, workers aged 55 and older accounted for 15.3 percent of the total labor force, up from 11.7 percent just five years earlier.

The occupation with the highest median age is farming at 51.9 years, while real estate agents and salespersons are an average age of 50.7.

Statistics Canada also revealed that a high proportion of bus drivers and other transit workers are already 55 or older. Senior managers in various fields, ministers of religion, school principals and university professors are the other fields dominated by older workers.
