In the UK, they sued the government on the grounds that the prohibition of silencers violated the OH&S laws requiring noise reduction at the source in the workplace. The people who were the focus of the lawsuit were those who had to use a firearm in the workplace. In the UK this was mostly professional stalkers.
It turns out our OH&S laws are virtually the same as the UK. Canadian Occupational Health and Safety Regulations section 7.5 states, “Insofar as is reasonably practicable, every employer shall, by engineering controls or other physical means other than hearing protectors, reduce the exposure to sound of employees to a level that does not exceed the limits prescribed by section 7.4.”

Maintaining the Canadian ban on sound suppressors is in actuality the federal government forcing Canadian shooters and hunters to expose themselves to damaging levels of noise that would not be allowed under Health and Safety regulations in the workplace. This is likely the only law on the books that says it is illegal for Canadians to protect themselves from a known health hazard. As such it is hypocritical and inconsistent with modern western values and quality of life.
The cost to the CDN economy of hearing damage is approximately $18 billion annually. This is a MAJOR health problem with major economic results.
Is there anything other than cost that is stopping people in Canada from doing the same thing?
Canada... WAKE UP.
