In any event, Mainstreet's numbers for Calgary's mayoral race and the subsequent opposite result thereto reminds me of Probe Research's numbers for the Winnipeg mayoral race back in 2014 with former NDP MP Judy Wasylycia-Leis held as the front-runner:

Again, it was a Winnipeg muni election akin to the Calgary muni election. Muni elections are completely different animals (for various reasons) that can "hoop" pollsters of all methodologies for that matter.
