More than 758,000 votes were cast at advance polls last week, smashing the previous record of 700,476 in 2019.

But Elections Alberta said Monday night only 67 of 255 tabulated advance voting locations had reported. It also noted some voting locations could not close until 9 p.m.

It's unknown when Albertans will know the results of the province's 87 ridings and who will lead the 31st legislative assembly.

Although Calgary has been cited as the deciding battleground, there are plenty of ridings to watch with every election offering its own surprises.

Results have been slow to come in but CBC News projects United Conservative Party Leader Danielle Smith (Brooks-Medicine Hat) and New Democratic Party Leader Rachel Notley (Edmonton-Strathcona) have won their ridings.

Former cabinet ministers Todd Loewen (Central Peace-Notley), Nate Horner (Drumheller-Stettler) and former Speaker Nathan Cooper (Olds-Didsbury-Three Hills) are also projected to win their respective ridings.

Calgary-Currie is projected to flip from UCP to NDP, leaving former minister of mental health and addiction Nicholas Milliken without a seat.

NDP stalwarts Janis Irwin (Edmonton-Highlands-Norwood) and David Shepherd (Edmonton-City Centre) are projected to be re-elected.

CBC News will be hosting live coverage throughout the evening. You can watch it here from 7:30 p.m. MT. A comprehensive list on how you can follow the election is listed below. 

Although there are many parties from either end of the political spectrum — from communists to separatists— the race is very much a rematch of 2019's contest between the UCP and the New Democratic Party.

A lot has changed since the UCP took the province four years ago. The world weathered the COVID-19 pandemic, the governing party chose a new leader, and oil prices have returned prosperity to the provincial coffers.

Danielle Smith leads the UCP, having won the leadership race this fall after Jason Kenney's resignation. This will be her second attempt at taking the premiership in an election, having led the Wildrose Party into 2012.

Rachel Notley, meanwhile, leads the NDP for her third election as leader. She won a four-year term as premier in 2015 before losing to Kenney in 2019. 

Both offer their own vision of Alberta's future. 

The long campaign

The election officially started on May 1, although campaigning began much earlier.

On that first day, Smith and Notley held Calgary kick-off events singing the refrain to songs that would play on repeat in the coming weeks.

Smith promised to keep taxes low. The UCP has pledged to make its first legislation an amendment so income taxes can only be raised through referendum.

Notley promised she would fix the health-care system. The NDP have committed to offering signing bonuses up to $10,000 to attract doctors, nurses and other health professionals.

Cost of living, health care, public safety and other issues have been as much the basis of attacks as of promises.

The UCP hammered Notley's plan to return the corporate tax rate to 11 per cent. The NDP lambasted Smith after she was found to have breached the conflict of interest act. And on it went.

Albertans were finally able to see the two leaders go head-to-head in the sole election debate on May 18, although the exchange hardly produced headline-making gaffes or declarations.

For many in the province, politics has been the least of their concerns. Wildfires erupted throughout central and northern Alberta in early May, threatening communities and forcing thousands to evacuate from their homes.

There were unsuccessful calls to postpone the election but Elections Alberta has said it will ensure every eligible Albertan gets to vote.
