CBC News: "The city of Prince Albert, Sask., activated its emergency operations centre on Saturday afternoon to put together a contingency plan after noting that a boom set up to contain an oil spill upstream on the North Saskatchewan River had been breached.
A pipeline break, reported by Husky Energy on Thursday, resulted in an estimated 200,000 to 250,000 litres of oil reaching the North Saskatchewan, entering the water near Maidstone, Sask.
Booms had been initially setup in that area to try to contain the spill."
