White Rose production will ramp up to reach full rates of approximately 20,000 barrels per day, net to Husky, by early next week, the company said in a statement. Husky owns 72.5 percent of the field and Suncor Energy owns the remainder.

Last year's spill of 1,572 barrels of oil was the largest ever recorded off the coast of the eastern Canadian province, the regulator Canada-Newfoundland & Labrador Offshore Petroleum Board said.

It was caused by a failed connector on an underwater oil flowline, which came apart during startup operations, a Husky investigation found.

"We regret the spill last year," Husky CEO Rob Peabody said in a statement. "As a result of our investigation, we've enhanced our startup procedures, strengthened equipment and added more barriers to prevent failures."

The company installed a replacement connector with a higher load capacity in July and has submitted an investigation report to the regulator.
