Online voting is more available than ever. So what effect does it have on voter turnout?

Voting online can be as easy as a few clicks from the comfort of your own home. That convenience is one of the reasons online voting is oftenpitched as a way to potentially increase voter turnout.

Ontario has allowed internet voting in municipal elections for almost two decades. Nearly fourmillion people were eligible to cast a ballot online in last month's elections, but a majority of them did not vote at all.

Figures compiled by CBC News suggest that in Ontario the technology has not had a significant impact on voter turnout.

"It's been a method of convenience for voters but it's not really the kind of thing that gets people out to vote," said Jon Pammett, a distinguished research professor in political scienceat Carleton University.

For this story, CBC collected data fromOntario municipalitiesthat have allowed online voting for at least two elections and each have more than 50,000 eligible voters. The full results from the 13 municipalitiesare below.

Online voting a 'novelty'

Seven municipalities (Peterborough, Sudbury, Cambridge, Kingston, Ajax, Chatham-Kent andSarnia) recorded a bump in voter turnout during the first year they introduced internet voting. Two others (Markham and Burlington) saw an increase in voter turnout in the secondelection after the technology was introduced.

Four of those municipalities (Cambridge, Kingston, Ajax, Chatham-Kent) continued to register an increase in the second election, but those gains have since been lost.

"The data tells us the novelty of the introduction gets a certain amount of attention and people go, 'Oh, something new,' " said DennisPilon,an associate professor of politics at Toronto's York University."But that doesn't last after a couple of uses. Now it's ordinary."

Markham and Peterborough have used online voting the longest. Markham has seen turnout trend upwardand largely stay in the mid to high 30 per cent range, while in Peterborough turnout has almost steadily declined from a high of 48to 40 per cent.

The remaining four municipalities (Brantford, Pickering, Kawartha Lakes and Newmarket) have only seen turnout decline since introducing online voting.

A 2018 study looking at Ontario municipal data from 2000 to 2014 found the technology can increase turnout by 3.5 percentage points.

"I do believe there is an effect on turnout.I believe it is a modest effect," said Nicole Goodman, an associate professor at Brock University in St. Catharines, Ont., and one of the report's co-authors.

Goodman cites other studies that found methods that make voting more convenient, for example mail-in voting, can increase voter turnout by two to four per cent.

"The effects of internet voting on turnout have always been a bit mixed," said Pammett.

He said the technology is helpful for those who may find it difficult to get to a polling station because of illness for example.

Pammett co-wrote a paper on internet voting for Elections Canada in 2010, but he said the agency has since dropped the idea. The federal government and several big cities, including Toronto, have ruled out using the technology, they say because of security concerns.

"[Online voting] is not on its own going to be able to engage people politically, get them interested in the election if they're really on the margin about voting in the first place," said Pammett.

Low turnout in 2022

Municipalities tend to have lower voter turnoutthan provincial or federal elections.To explain this, experts point to a myriad of factors, including what Pammett calls "an information gap."

"People, although they might like to vote, don't feel very comfortable about voting if they're unsure what they're voting for."

Ontario doesn't allow political parties at the locallevel, socandidates run as individuals without party affiliation.

York University's Pilon said political parties can help voters understand where a candidate falls on a certain topic

Renan Levine, who teaches politics at the University of Toronto,notesthat another factor is a decline in local media, with national and regional media focusing primarily on races inbig cities.

"Some of the things that jump out at me from this data is that we don't see across the board clear patterns," said Levine. "[That] would suggest that a lot of what we're seeing here has to do with very local factors."

That could include non-competitive races, he said.

Voter turnout in Newmarket, Ont., for example, has stayed in the mid to low 30 per cent rangefor several elections, but dropped 10 percentage points this year.

The town's clerk, Lisa Lyons, pointedout that in last month's poll the mayor and two ward councillors were acclaimed, meaning no one ran against them, "which historically impacts voter turnout."

Provisional data from the Association of Municipalities of Ontario suggests overall voter turnout across the province hit33 per cent, down from just over 38 per centin 2018.

Experts say it's not clear why turnout dropped, but they also point to a historic low turnout in Ontario's provincial election, which dipped to 43 per cent in June.

"To see the kinds of results we've seen provincially suggests that maybe there's a bigger problem in terms of voter engagement," said Pilon.

Estonia's experience

At the federal levelvoter turnout has stayed in the 60 per cent range in all but one of the last 10 elections.

NeitherPilonnorPammettbelieve introducing online voting in federal elections would lead to higher turnout.

"Internet voting is a great opportunity for people who are already committed to vote," Pilon said, adding it just gives those voters another option.

Figures from Estonia support their view. The eastern European country was the first in the world to allow online voting in national elections.

Since 2007 the country has held four votes, but turnout has stayed in the low to mid 60 per cent range.

"It's stable, comparable to the period before the introduction of internet voting," said Mihkel Solvak, an associate professor of technology research at the University of Tartu in Estonia.

"The explanation behind this is that actually, your typical voters who previously voted on paper have gradually switched to internet voting."

Nearly half of voters in Estonia are now voting online,Solvaksaid.

The country decided to introduce the technology to boost youth voter turnout, but he said turnout in the 18-25 age group is actually down.

"We cannot fix low turnout with technology, that is the biglet's say lesson out of the actual implementation of internet voting."

West Virginia study

Solvaksaidthat internet voting can make a difference for overseas voters.

A study out of the United States backs that up.

Anthony Fowler is a professorin the University of Chicago's school of public policy. He studied voter turnout in West Virginia, which he said was the first state to allow overseas voters to cast a ballot online in the U.S. federal midterm election in 2018.

Fowler said nearlyhalf of the state's counties opted to allow online voting, so he was able to compare those who could vote online versus those who had to vote by mail.

"I estimate that turnout increased among the [online] group by something like three to five percentage points," he said.

"That's not a massive effect, but that's bigger than the effects of lots of other kinds of performances, certainly bigger than lots of get out the vote efforts."

Goodman, who studies online voting at Brock University, saidmore research is needed to understand the overall impact of online voting on turnout.

"I don't think we've necessarily had the right data or experiences in which to study or examine this problem."

More people are voting online

Several Ontario municipalities including Kingston, Markham and Burlington point out that the overall percentage of votes cast online is going up in each election.

Some cities, though, have scrapped or limited paper ballots, so internet voting is the only option.

Nicole Cooper, the clerk in Ajax, which saw voter turnout decline by 10 percentage points this election, said exit surveys suggest residents "overwhelmingly" support internet voting.

She said thetown will continue to offer the technology.

Mark Guinto, a spokesperson for neighbouring Pickering, said that's also the case for his city.

"In an era of declining voter turnout, it's critical that we provide our residents with more accessible and convenient voting options."
