NDP flips Calgary-Shaw as UCP faces questions over vote splitting and separation debate

Alberta’s New Democrats have captured Calgary-Shaw in a closely fought byelection, overturning a longstanding United Conservative advantage in the south Calgary riding. NDP candidate Kyle Campbell received 7,461 votes, defeating UCP candidate Mike Derry by 582 votes. Campbell finished with approximately 46.6 per cent of valid ballots, compared with 43 per cent for Derry. The results remain unofficial until Elections Alberta completes its verification process on Sept. 24.

Premier Danielle Smith’s office attributed the loss primarily to low turnout and vote splitting, pointing to the 978 ballots cast for Progressive Tory candidate Kyle Joseph. That total exceeded Campbell’s margin of victory, but it cannot be assumed that every Progressive Tory voter would otherwise have supported the UCP. Progressive Tory Leader Peter Guthrie rejected the vote-splitting argument, maintaining that his party is appealing to conservatives who no longer identify with Smith’s government.

The result has also intensified debate over whether Alberta’s Oct. 19 separation referendum is hurting the governing party in Calgary. Former premier Jason Kenney and several conservative strategists characterized the defeat as a warning about the political cost of entertaining separation, while NDP Leader Naheed Nenshi said voters were also focused on health care, education and affordability. Although a low-turnout byelection cannot reliably predict a general election, losing a traditionally conservative constituency underscores the UCP’s vulnerability in Calgary, which is likely to remain the decisive battleground in the 2027 provincial campaign.
