Our Politics Panel looks at the implications of the Trans Mountain pipeline showdown between B.C. and Alberta and examines Jason Kenney's shrinking UCP caucus.

Is Alberta on the brink of a trade war with B.C?

Premier Rachel Notley is piling on the pressure in the B.C. pipeline dispute. She’s calling for federal intervention in response to the latest hurdle being thrown up by the Horgan government to the Kinder Morgan expansion.

The Prime Minister has said the Trans Mountain Pipeline project will go ahead, but indicates he has no intention of getting between two squabbling provinces.

The latest salvo by Alberta was delivered Tuesday, with Premier Notley announcing an immediate boycott on the importation of all B.C. wines.

Jason Kenney parts ways with two UCP MLAs

Two MLAs will not be returning to the UCP caucus.

The party issued a terse statement last Friday indicating Don MacIntyre, the Member for Innisfail-Sylvan Lake had resigned. That will trigger a by-election sometime over the next six months.

The United Conservative Party is done with Derek Fildebrandt. The former Opposition Finance Critic was forced to leave the UCP caucus six months ago after a series of embarrassing scandals and any hopes of returning were dashed Friday when party leader Jason Kenney indicated he is out for good.

Our Politics Panel is made up of: Graham Thomson, Edmonton Journal political affairs columnist; Robert Noce, lawyer and former Edmonton city councillor and Lori Williams, political scientist, Mount Royal University.
