Fewer people tend to vote in municipal elections in Edmonton than in Calgary. We look at why

More Edmontonians cast a ballot in this year's municipal election than in the four elections prior, but overall turnout was higher in Calgary ― again.

The 2021 Calgary election had a voter turnout of 46.36 per cent. Data shows that this follows a pattern since at least 1983 ― the oldest year publicly available to compare both cities ― where Calgary usually has higher turnout than Edmonton. Sometimes significantly so.

There are several hypotheses about why this may occur, political experts say. But there is a theory that suggests competitive races create a sense of urgency and drama that engages people.

"People in Calgary have just come to expect fiery municipal elections and it engages them. Edmontonians are just used to more subdued municipal elections," said Janet Brown, a pollster and political commentator.

"Competitive elections tend to drive turnout," said Jack Lucas, a University of Calgary political science associate professor.

Data shows about a third of eligible voters in Edmonton usually vote municipally. There have been a few years where that trend wavered: In 1992, Jan Reimer faced a tight race for re-election against Bill Smith. There was a 51.7 per cent turnout.

In 2007, Stephen Mandel won re-election by a large margin, with just over 27 per cent turnout.

In Calgary, turnout fluctuates more often ― yet the city usually has a higher turnout than Edmonton. There have been 13 municipal elections since 1983. Calgary topped Edmonton's voter turnout in eight of them, including the last five.

Sometimes the turnouts have been close, such as in 2001 when Calgary saw 37.7 per cent of voters versus just over 35 per cent in Edmonton.

Other times, less so. In 2017, Calgary saw a voter turnout of 58.1 per cent ― nearly 27 per cent more than Edmonton, which hasn't seen a turnout that high since 1966, when 59.9 per cent of voters cast their ballots.

Calgary calculates voter turnout using the number of eligible voters provided by Elections Alberta, a city spokesperson said.

Edmonton Elections has relied on estimated voter information gathered through the municipal census in past elections. That information was unavailable for the recent election, so the number of eligible voters was estimated based on city and provincial statistics, according to a city spokesperson.

Brown has led focus groups with voters following the municipal election in an effort to gauge how they felt about it and how engaged they were.

Her research has led her to form a few hypotheses about why voter turnout was higher in Calgary, such as the plebiscite about reintroducing fluoride into the city's drinking water, which she said may have spurred more people to get out to the polls.
