Ontario's Liberal government is promising legislation to mandate workers compensation coverage for the construction industry.
Labour Minister Peter Fonseca says the bill would extend compensation coverage to about 90,000 construction workers.
Fonseca says making insurance coverage mandatory in the construction sector will help make Ontario's workplaces the safest in the world.
The Building and Construction Trades Council of Ontario says the proposed legislation will close a loophole that has been exploited by unscrupulous contractors.
The council says the bill will also level the playing field for bidding on construction projects because companies that were not paying insurance premiums have had an unfair advantage.
Construction companies also hope their insurance premiums will be lowered as the pool of those contributing is expanded.
