Oil major ConocoPhillips is laying off 400 employees and 100 contractors in Canada, a company spokesman said on Sept. 1, with the majority of cuts coming in the Calgary office.

ConocoPhillips spokesman Rob Evans said the 400 employees were about 15 percent of the company's workforce in Canada and the cuts will take effect in mid-October.

Conoco is reducing its global workforce by 10 percent on average as low oil prices bite.
