Members of a First Nations group vying to buy an ownership stake in the Trans Mountain pipeline expansion will be in Calgary on Thursday.

Two founders of Project Reconciliation, executive chair Delbert Wapass and managing director Steve Mason, will be taking part in an energy industry panel discussion.

The federal government approved the Trans Mountain expansion project on Wednesday and said work on the line would be completed by 2022.

Canada's Natural Resources Minister Amarjeet Sohi, speaking on CTV Morning Live Calgary, said TMX is an incredibly important project for Canada.

"I have been working on this project ever since I got elected but specifically when I was named Minister of Natural Resources and since the Federal Court of Appeal decision came out quashing the first approval."

Sohi said since that time, the focus has been on fixing the process.

"Now that the approval is given, we will issue a certificate in the next couple of days and Trans Mountain corporation can start to apply for permits."

Once the permits and all other necessary pieces are in place, Sohi says construction could start in September.
