Ottawa police say the coronoer has confirmed that a human foot was sent to the Conservative Party of Canada's headquarters on Tuesday.
Police say a call about a suspicious package at 130 Albert St. came in around 11:20 a.m.
According to police, all emergency services responded to the call, including a Hazardous Materials and Items team (HazMat).
The package, which police confirm was sent through Canada Post, was partially opened when police arrived.
Police also say the package possibly had blood stains on it.
CPC spokesperson Fred Delorey would only confirm that "a suspicious package was sent to our office" and directed all other questions to Ottawa police.
The major crime unit is now in charge of the investigation. RCMP officers are also on scene.
