Husband and father Samatar Sahal, 40, was killed while working at a Trans Mountain pipeline site in west Edmonton on Tuesday.

Alberta's premier says Trans Mountain announcing it will resume construction on its pipeline expansion project is a step forward, but not a reason to celebrate.

The National Energy Board has approved construction on the Trans Mountain pipeline extension between Edmonton, Alta., and Kelowna, B.C.

In a recent SEC filing, Kinder Morgan revealed that the Trans Mountain twinning will cost $1.9 billion more and take an additional year to complete.
