The size of the average weekly paycheque for non-farm work in Canada grew slightly in June and was 2.6 per cent higher than the same time last year, Statistics Canada reported Wednesday.

Month to month, payroll earnings inched up 0.2 per cent between May and June to $919.

In the 12-month period that weekly earnings rose, the average number of hours worked per week decreased by 0.6 per cent.

The average annual pay increase last June was higher, at 2.8 per cent, but during that period Canadians saw an increase of 0.6 per cent in the number of hours they worked.

Administrative, support services see biggest bump

The biggest increase in earnings between June 2012 and June 2013 was in administrative and support services, where paycheques grew by 8.1 per cent over 12 months to $764.

The accommodation and food services sector saw weekly earnings contract by 2.2 per cent to $362.

"Declines were concentrated in full-service restaurants and limited-service eating places," the agency said.

Employees in professional, scientific and technical services earned the most, with average weekly earnings of $1,273 in June (up 3.6 per cent over June 2012). The biggest earnings growth in this area was in scientific research and development services and computer systems design and related services.

Alberta and Saskatchewan had the highest year-over-year growth among all provinces for the fifth consecutive month while Manitoba, New Brunswick and Prince Edward Island saw earnings grow by less than one per cent over 12 months.

The data does not capture the effect of the Quebec construction strike but might reflect some effects of the flooding in southern Alberta in June, the agency said.
