Alberta’s chief electoral officer has confirmed a byelection date for a Calgary riding vacated earlier this year. Chief Electoral Officer Gordon McClure said Monday the writ was issued to hold the byelection in the riding the of Calgary-Shaw on Sept. 14. The seat for that riding has been vacant since May when former minister of environment and protected areas Rebecca Schulz resigned after a recall petition was launched against her. The United Progressive Conservatives and NDP have both named candidates who will represent them on the ballot. Premier Danielle Smith says Mike Derry, who is a former oil executive, would be a strong voice for the riding in Edmonton. NDP Leader Naheed Nenshi, meanwhile, says his party’s candidate Kyle Campbell can help Albertans send a message to Smith to stop catering to separatists. Candidate nominations are open until Aug. 27 at 2 p.m., and advanced voting runs from Sept. 8 to Sept. 12. Anyone who is a Canadian citizen at least 18 years of age on election day who lives in the riding can cast a ballot. Electors can register to vote online until Sept. 2, or can register at their assigned voting location on election day.
