Alberta’s front-line health provider says it will stop awarding contracts to firms at the centre of an auditor's investigation into what the Opposition NDP calls unprecedented allegations of corruptio

A letter obtained by the Globe and Mail allegedly accuses the UCP of widespread corruption, conflicts of interest and firing the former CEO of AHS because she tried to investigate.

Nenshi says Smith, as well as Health Minister and Red Deer-North MLA Adriana LaGrange, plus Andre Tremblay, who heads day-to-day operations of the province’s health system, should resign while investigators, the RCMP included, investigate.

Alberta NDP Leader Naheed Nenshi is calling for four investigations and for Premier Danielle Smith to answer questions on what he calls unprecedented allegations of high-level corruption into medical purchases and surgery contracts.
