Police are now looking at two parks in the same area of Toronto, where razor blades have been found scattered on the ground.
Officers put out a public safety alert after blades had been found in June Callwood Park, near Lakeshore and Strachan.
A woman walking her dog made the original discovery and reported it to police.
But now, blades have been found in Lisgar Park near Queen and Ossington.
There have been no injuries but police are looking to find the person responsible.
Officers tell NEWSTALK1010 that the case is considered suspicious, but they haven't officially linked the two incidents despite blades at both parks being similar.
