Concerned about prevalence of cancers and poor support for sick workers by mine owners, United Steelworkers representatives had been meeting with the Government of Ontario, the leader of the opposition New Democratic Party, and the Workman's Compensation Board of Ontario.[5] At the time, the union activities were led by Gib Gilchrist, who was supported by Paul Falkowski and Homer Seguin.[6]
Immediately prior to the strike, two representatives of United Steelworkers, attended a conference in Bordeaux, France. At the conference, they learned about a paper presented by the Ontario Ministry of Health that contained details about cancer risks to uranium miners, that had not been shared with the miners.[5]
Ed Vance, one of the striking miners, is quoted in the 2016 book Health and Safety in Canadian Workplaces:[7]
"They deliberately kept us ignorant. There is no other way to describe it. Government has a responsibility and in this case they failed to keep the workers advised. They failed to warn the workers of their work environment. And, they were part of that conspiracy."[7]
Mine owners immediately allowed miners to change the filters in their protective face-masks daily, an improvement from the existing weekly replacements, and soon after offered a 15 cent per hour increase in living allowance.[5]
The government embarked on air-quality testing in the mines, but was criticized for missing some areas.[5] Following the survey, mine owners improved underground ventilation.[5]
Pressure from the workers, combined with the political pressure, led to the creation of the Royal Commission on the Health and Safety of Workers in Mines,[2] informally known as the Ham Commission after its chairperson, James Milton Ham.[1]
The recommendations from the royal commission led to the creation of Ontario's Occupational Health and Safety Act of 1979.[2][3][4]
