TC Energy expects cost of Coastal GasLink pipeline project to rise

The Coastal GasLink pipeline is not the only major energy infrastructure project in Canada to be plagued by cost overruns this year. In February, the company behind the ongoing Trans Mountain pipeline expansion project — which will increase oil transportation capacity from Alberta to the West Coast — announced the new cost of the project is an estimated $21.4 billion, up from an earlier estimate of $12.6 billion.
