Official results are not a current roster.

These are official results for the 28 April 2025 general election. They are historical election records, not a claim about the current House membership or future candidacies.

Candidate policies, biographies, political finance, current tenure, and future candidacy remain separate sourced layers. Electionpedia does not manufacture them from a vote result.

How to interpret this record

Markham—Unionville Election Result 2025: Michael Ma Won

An election result is a dated publication about a defined contest and reporting area. Certification status, ballot accounting and the voting system determine what the numbers can support.

Identify the election and the reporting stage

A preliminary publication, an election-night update and a final certified result describe different stages. Electionpedia retains the source’s status rather than treating every displayed number as final. For historical research, the source version remains important because later corrections can change a total without changing the identity of the election.

Read the denominator

A vote share needs a denominator: candidate votes, valid votes, ballots cast or another published base. Turnout can use a different base again. Compare the labels before comparing percentages. A margin in votes and a margin in percentage points answer related but different questions.
