In a year-over-year comparison, employment across Canada grew 1.4 percent, or 250,000 full-time jobs and the total number of hours worked increased 1.1 percent.
The employment gains were in the private sector and offset losses from the two previous months, Statistics Canada reported.
In May, employment increased in Ontario, Quebec, Alberta, New Brunswick and Manitoba but declined in Prince Edward Island.
Employment gains in May were recorded among youths and people age 55 and over, Statistics Canada said.
Little change was noted for the 25-to-54 group.
Employment gains were reported in construction, retail and wholesale trade, "other services," and business, building and other support services.
