WINNIPEG, Manitoba, March 5 (Reuters) - Cenovus Energy ( CVE )

, Canada's third-largest oil producer, said on Tuesday

it plans to boost energy production by 19% during the next five

years as the country's pipeline capacity expands.

Canada's heavy oil sells at a discount to the North American

benchmark in part because of limited export pipeline capacity.

Expansion of the Canadian government-owned Trans Mountain

pipeline, expected to be completed in the second quarter, will

expand shipping to refineries on the U.S. West Coast and in

Asia.

Canadian oil producers are modestly expanding output to take

advantage of the expansion, which will nearly triple Trans

Mountain's capacity to 890,000 barrels per day.

"This represents a new pathway into global markets," said

Chief Commercial Officer Drew Zieglgansberger at Cenovus's

annual investor day in Toronto.

Cenovus said it plans to raise production by 150,000 barrels

of oil equivalent (boe/d) to 950,000 boe/d by 2028.
