Markham voters should watch their mail for the information they will need to cast an online ballot in the 2026 municipal election. Voter Information Letters are being delivered by Canada Post to registered voters, according to a City of Markham news release issued Oct. 7.

Online voting opens Oct. 16 at 10 a.m. and closes Oct. 26 at 8 p.m. Eastern time. Voters will choose representatives for the offices of mayor, regional councillor, ward councillor and school board trustee.

The letters contain the address of the city’s online voting website, a personal voting PIN and other election information. The PIN is intended only for the voter to whom it is assigned.

Voters also have an in-person option. They can cast a ballot at any designated voting place from Oct. 23 to 26, or at Elections Markham Headquarters until Oct. 22.

What to do if your letter does not arrive

Eligible voters who have not received a letter by Oct. 16 may not be registered, or their registration may not reflect their current address, the city said.

Registration details can be checked and updated through Elections Markham’s online Register to Vote service. Voters can also do so at the Legislative Service counter at Markham Civic Centre or at any voting place during the Oct. 23–26 in-person voting period.

Anyone registering in person should bring identification to establish their identity with election officials.

The city’s notice lists an age requirement of at least 18 by Oct. 26, 2026, and a connection to Markham as a resident, landowner or tenant, or the spouse of one. Owning or renting more than one property in the city does not allow a voter to cast more than one ballot.

Keep your voting PIN private

If a voter loses their letter, they should contact Elections Markham for a replacement online voting PIN. The previous PIN will then be deactivated.

A letter addressed to someone who does not live at the recipient’s address should be marked “Return to Sender” and mailed back to Elections Markham.

The city cautions voters to open only letters addressed to them, noting that taking or opening another person’s mail is illegal. It also says voters should not share their PIN and that no one should ask them for it.

Elections Markham’s official website provides election information. The division is independent and non-partisan and is responsible for delivering city council and local school board elections, by-elections and referendums.
