Information Checking my votes

[AbleistSL]

I am concerned about my vote having an error and I would like to be able to check it.

Is this possible in canada?

No. If you put it in the ballot box, it stays there until close of polls on Monday.

I suspect you cannot.

Vaguely remember this issue coming up in the US election, people who voted for Biden, found out one of his policies they didn't like, wanted to switch, and too late.
