On Sunday, Federal by-elections were announced in four ridings across the country, including Portage-Lisgar. Voters will head to the polls Monday, June 19th. A by-election became necessary in the riding after former Conservative Portage-Lisgar MP Candice Bergen resigned her seat in the House of Commons earlier this year.

Canadian citizens in Portage–Lisgar who are at least 18 years old on election day are eligible to vote in their electoral district if they:

- Live in their electoral district from Monday, May 15, 2023, to Monday, June 19, 2023.
- Are registered. Most Canadians who are eligible to vote are already registered in the National Register of Electors. To check if you are registered, or to register to vote, electors should use the Online Voter Registration Service at elections.ca, call 1-800-463-6868 or contact their Elections Canada office. You can also register in person at their polling station when they go to vote.
- Show proof identity and address. There are many different pieces of ID that can be used to prove identity and address. The full list is available online.


Advance polling days will be Friday, June 9th, Saturday, June 10th, Sunday, June 11th, and Monday, June 12th.

Conservative Party of Canada candidate Branden Leslie, and People's Party of Canada leader Maxime Bernier will be running for their respective parties. At this point, there's no word on candidates from any other parties.

In the September 20th, 2021 general election, the Conservatives won the riding, with Candice Bergen as candidate, with 52.5% of the vote. Solomon Wiebe, from the People's Party of Canada, came in second with 21.6% of the vote.
