Anyone who tweets or posts election results online before the last poll closes next Monday could result in a $25,000 fine, Elections Canada says.
But despite that warning, the agency will not be monitoring social media, instead it says it will rely on the honour system, and if complaints are filed, the agency will then investigate.
A 1938 law aimed at telephone and radio use bans election results to be transmitted until the last polls on the West Coast close.
But social is quickly changing the way information travels.
One political expert argues knowing results in one part of the country can change voting behaviour elsewhere.
"The question is a can you enforce it and are you willing to take steps to enforce it? One way they could enforce it is not to release the results until all the results are known," said Duane Bratt with Mount Royal University.
Elections Canada says that change would have to come from parliament. It also maintains it will not be monitoring social media sites on Election Day.
But one social media expert thinks that is a mistake.
"To monitor Twitter and all social media in a sense is absolutely possible… that is an absolute mistake, you cannot arm yourself with education without listening," said social media expert Walter Schwabe.
There have been no breaches of Bill 329 in the last three general elections.
A fine was issued in 2000 when a blogger posted early results. That case went before the Supreme Court. The man was handed a $1,000 fine.
