Montreal police said on Wednesday that a foot found on the street by a passerby is a fake.
The false limb was spotted about 7:40 a.m. next to a sidewalk in the city's west end.
The discovery was first reported by police to be a human foot. But they later said it was rubber.
The discovery comes one day after human remains were mailed to two Vancouver schools.
Vancouver and Montreal police are working to determine if the human remains are linked to the Luka Magnotta case, which began with the grisly discovery of a human foot and hand mailed to the Ottawa offices of the Conservative and Liberal parties last week. Those body parts were identified as belonging to 33-year-old Lin Jun, a Chinese national who was studying at Concordia University.
Mr. Magnotta is not fighting his extradition and could be aboard a government-funded private jet to Canada within a month, German officials said as the 29-year-old Montrealer accused of a grisly dismemberment-killing waited in a Berlin prison cell.
