Former Saskatchewan Premier Brad Wall has a new job in Calgary as a special adviser for law firm Osler, HoskinandHarcourt LLP.

The firm announced the move on its website Tuesday. The news release says Wall will be based in Osler'sCalgary office.

Wall posted a tweet on Tuesday which said he would remain in his hometown of Swift Current.

"Our firm and our clients will benefit enormously from the strategic insights, practical business solutions, and collaborations Brad Wall has formed over a stellar political career," anemail by the firm obtained by CBC said.

Wall announced his retirement from politics back in August, in the middle of his third term in office and after more than a decade as the most popular premier in Canada.

Firm experienced in energy, pipeline sector

Osler represented Kinder Morgan in its application to the National Energy Board to expand the Trans Mountain pipeline.

In May 2016, the NEB approved the expansion. It was approved by the Trudeau government in Nov. 2016.

According to a company spokesperson, Oslercontinues to represent Kinder Morgan in "regulatory litigation proceedings" involving the Trans Mountain project

The project has caused tensions in recent weeks between the British Columbia, Alberta and Saskatchewan governments. Last week, Saskatchewan introduced legislation which could limit export of energy products to B.C. Alberta had previously done the same.

The federal government said it supports the project. Kinder Morgan has given a deadline of May 31 for the project to get underway.

Subject to Sask. lobbying rules

Wall stepped down as premier in January.Scott Moe became premier after beingchosen as the new leader of the Saskatchewan Party.

Wall is not allowed to lobby the Saskatchewan government for the 12 months following his resignation.

His new employer is not listed on the Saskatchewan LobbyistRegistry.

Minister of Export and Trade Jeremy Harrison said it is not uncommon for former premiers to become consultants or advisers, and he wished Wall well in his new role.

Harrison also said he does not believe the provincial government has a relationship with Osler, Hoskinand Harcourt.

"We have no relationship with the law firm as far as contractual relationship or anything like that."

Wall was elected as an MLA in 1999, servingthe riding of Swift Current.

He then became Saskatchewan Party leader in 2004 and won the 2007 provincial election, where he took office until his retirement.
