Calgary, Alberta-based Husky declined to say how many jobs were affected by the cuts.
"Husky has been taking steps to better align the organization and workforce with our capital plan and strategy," spokeswoman Kim Guttormson said in a statement.
The layoffs come a day after Canada's federal election, in which Liberal Prime Minister Justin Trudeau failed to secure an outright majority of seats, leaving him in need of support from left-leaning parties that are opposed to new oil pipelines.
That was the worst-case scenario for the energy sector, which fears the result could further delay the Trans Mountain pipeline expansion and deter investment in the oil and gas industry.
Husky shares were last up 4.3% at C$9.56 on the Toronto Stock Exchange. The company reports its quarterly results on Thursday.
