A grandfather working for his family's painting business died after falling from the roof of a Real Canadian Superstore earlier this summer, Manitoba Workplace Safety and Health says.

Around 3:30 p.m. on June 30, the man fell from the roof of the Superstore at 1578 Regent Ave. in Winnipeg, a spokesperson for Safety and Health said. The business, Jedi Painting and Decorating, was a contractor at the store.

The man was taken to hospital and later succumbed to his injuries.

Manitoba Workplace Safety and Health is investigating the incident and has issued a stop work order to the contractor.

Tyler Owens, who owns the painting service based in Selkirk, Man., told CBC News in a Facebook message that the man who died was his grandfather, but declined to comment further out of respect for his death.

A provincial spokesperson said in an email the province can't comment on the matter because it's still under investigation.

A spokesperson from Loblaws, Real Canadian Superstore's parent company, also declined to comment because of the ongoing investigation, but did offer condolences to the painter's friends and family.

From 2008 to 2017, the Manitoba Workers Compensation Board recorded 14 workplace-related deaths as the result of falls from height, she said. The board recorded 307 workplace fatalities in total in that time span.

Workplace Safety and Health conducts targeted enforcement at workplaces across the province to ensure risks are effectively managed, she said.

"Fall protection when working at heights continues to be a priority for [Workplace Safety and Health] inspections," she wrote in an email.
