Katie Reise, 31, and Chris Vollmershausen, 30, said they have distributed 75 ballots among friends and family to help them choose between Oscar, Winston and Finley if the baby is a boy, and Libby, Molly and Faye if the baby is a girl, the Toronto Star reported Wednesday.
The couple said the ballots have to be turned in by Thursday and no write-in votes will be counted.
"We're 100 percent committed to going with whatever name wins -- and just to make sure I don't feel tempted to sway the vote after it's in, I'm not going to vote myself," Vollmershausen said.
However, Reise said she plans to cast her own ballot.
"Personally, I think babies grow into their names, so I'd be OK with any of the choices," she said.
