A 41-year-old father of three died while shovelling snow behind his Toronto home on Monday afternoon after he collapsed from an apparent heart attack.

James Mangabay was clearing a big pile of snow in the alley behind his home on Northland Avenue, in the Keele Street and Road area, when he collapsed.

"We have a sudden death investigation. It appears it was caused by shovelling," Toronto police Sgt. Glen McBryde said at the scene.

Toronto Hydro employee Hart Blair, who was working nearby, administered CPR, but it was too late.

"It was awful because I didn't see any vital signs," Blair told CTV News.

Keith Landry, Mangabay's next door neighbour, was shocked and saddened by the incident.

"He told his wife that he was going to go out and shovel this morning. I can't believe this happened," Landry said. "I wish I was there to help him."

Snow clearing services for seniors

Following the first major winter storm of the year, which dumped between 26 and 30 centimetres of snow around Toronto, emergency and medical officials are reminding residents to be careful while clearing snow.

There are a number of snow-clearing services for seniors offered by the city, community organizations and businesses.

Elderly or disabled residents living in Toronto's core can sign up for the city's free snow removal service by visiting their website or calling 416-392-7768.

Seniors living in north Toronto can take advantage of the student assistance organization SAINTS, while Etobicoke residents can contact CANES Home Support Services.

Companies generally charge between $8/hr and $15/hr for their snow clearing service.

Snow shovelling tips

Toronto EMS reported a 33 per cent spike in calls following Sunday's storm for problems such as chest pains, breathing difficulties, fainting and falls, in relation to snow shovelling incidents.

Here are some snow shovelling tips from the Ontario Chiropractic Association:

  • Warm up before lifting (such as taking a 10-minute walk)
  • Don't let snow pile up (shovel small amounts frequently)
  • Use a lightweight shovel
  • Push snow (don't throw it)
  • Bend your knees and keep your back straight
  • Take frequent breaks
  • Call 911 if you feel chest pain or other serious symptoms
  • Stretch afterwards
