Kinder Morgan says it expects to restart its Trans Mountain pipeline later Tuesday.
The Alberta-to-West-Coast line was taken down for repairs after a small amount of crude leaked over the weekend.
The company inspected the site of the spill, 150 kilometres west of Edmonton overnight, and found no free oil when it dug up the pipe.
High water levels and wet soil initially hampered access to the pipeline.
The Trans Mountain pipeline has the capacity to carry 300,000 barrels per day of crude oil and various refined products.
It starts near Edmonton and ends up at terminals in the Vancouver area and in Washington.
