Toronto police were called to the home of Ontario Premier Doug Ford on Tuesday because of a suspicious package, the premier's office says.

"At this time, I can confirm the Toronto Police Services were called to the Premier's home today to investigate a suspicious package," Ivana Yelich, spokesperson for Doug, said in an email to CBC Toronto.

The package was sent in the mail and was received by his wife, Karla, Yelich said. She is said to be safe.

"The TPS quickly mobilized to assess the situation and cleared the family of any harm," Yelich said.

"The substance was determined to be a mixture of non-toxic materials," she added.

Police's special tactical units responded

Const. Alex Li, spokesperson for the Toronto Police Service, said officers were called to the area of Kipling Avenue and Eglinton Avenue West, near where Ford lives, at about 2:10 p.m.

Special tactical units also responded to the call.

"The package has been deemed safe, and there is no risk to public safety," Li said in an email on Tuesday.

He would not confirm that they were called to the premier's home.

Toronto Paramedic Services and Toronto Fire Services were also called to the address at that time. Paramedics said the call was cancelled at the scene.

Toronto Fire District Chief Stephan Powell said firefighters have left the scene after it was determined there was no hazard.

The premier's office thanked the police for their "tremendous work."
