Statistics Canada says the number of job vacancies was up 3.8% in September at 994,800.
The agency says the month-over-month increase was largely attributable to seasonal variations, as job vacancies typically peak in September.
The number of vacancies in the accommodation and food services sector rose 12.0% to 152,400, while the construction industry saw a gain of 14.0% to 93,900.
The number of vacancies in manufacturing was down 11.3% at 76,000 in September.
On a year-over-year basis, Statistics Canada says the total number of job vacancies was little changed.
The job vacancy rate, measured as the number of vacant positions as a proportion of total labour demand, was 5.7% in September, up from 5.4% in August, but down from 5.9% in September 2021.
