City hall will recognize workers who have been injured or killed on the job or became ill as a result of their work.
A formal ceremony will be held in the council court yard on Monday -- recognized across the country as the National Day of Mourning -- from 9 to 9:30 a.m.
"The National Day of Mourning is a day in which we should take a moment to remember workers who have suffered as a result of their occupation," Mayor Sam Katz said. "The City of Winnipeg employs thousands of people whose chosen career path requires a high level of vigilance in order to reduce risk.
"The city is committed to providing a safe work environment."
Civic employees and the public are invited to attend the ceremony.
In addition to the formal ceremony, flags flying at civic properties will be lowered until sunset on Monday.
