Police say while the images may be offensive, they don't break any laws so they won't be investigating further.
Robert Rudachyk had filed a complaint with police on Friday against the two anti-abortion groups behind the campaign.
Campaign Life Coalition Youth and the Canadian Centre for Bio-Ethical Reform sparked controversy this week for dropping the graphic leaflets in mail boxes across the city.
The flyers show photos of aborted fetuses and Liberal Leader Justin Trudeau.
The leaflets target Trudeau for his move to ban anyone who doesn’t support abortion rights from running as a candidate for the Liberals.
"I do not appreciate having filth like that put where my children can see it possibly and I don't believe that stuff should be put in anybody's mail box unwillingly," said Rudachyk.
"My next-door neighbour's five-year-old granddaughter went and got the mail yesterday, saw this thing, and promptly vomited on the floor. She was so frightened by the pictures."
Rudachyk is among many parents who have expressed concern about their children seeing the images.
"It was very shocking. I'm not easily shocked, but it was disgusting, honestly," Ali McIlmoyl said after finding one in her mailbox.
