Outgoing ambassador calls Keystone very important

US ambassador to Canada leaving before Keystone resolved but says problems taken "in stride"

TORONTO (AP) -- Outgoing U.S. ambassador to Canada David Jacobson says the Obama administration knows how important the controversial Keystone XL pipeline is to Canada but he won't speculate about how much it would damage the relationship should it not be approved.

David Jacobson, who leaves July 4 after a four-year stint, said in an interview with The Associated Press on Monday that he's most proud of the fact that when problems arise between the countries people take it in stride and "don't go off the reservation." But Jacobson is leaving before the president decides whether to approve the pipeline, which would carry 800,000 barrels of oil a day from Alberta across six U.S. states to the Texas Gulf Coast. A decision is expected this year.

Jacobson calls it a "very important decision."
