A human foot has been found among mounds of trash brought to Buffalo from a transfer station in Toronto.

Toronto police received a call from authorities in the U.S. informing them of the discovery at about 9:15 p.m. on Monday.

The foot was found by an employee of the Buffalo transfer station while he was sorting recyclable materials on a conveyor belt. It is unknown if the foot belongs to a man or a woman.

The transfer station is located in the Seneca region of Buffalo. Toronto police spokesperson Const. Tony Vella said police in Seneca are going through the trash at the facility while police in Toronto's 22 Division are are searching a transfer station in the city's west end.

He would not specify which transfer station is being investigated.

Vella told ctvtoronto.ca.  it is "unclear at this time" when the Toronto waste was transferred to Buffalo.

Toronto went without garbage collection for five weeks because of a civic strike.

Over the weekend, cleaning crews collected 25,000 tonnes of trash that had been dumped at garbage sites throughout the city. By 1 a.m. Sunday, crews had cleared the last bags.

Torontonians had the option of dumping their trash at 26 temporary sites that were set up in neighbourhood parks or dropping off a limited number of bags at transfer stations that were being monitored by picketers.

Regular curb-side garbage and recycling collection resumes today.

Vella said he's not clear which Toronto police division is investigating the incident.

The foot was being held at a U.S. medical examiner's office.
