A new study shows just how well face masks stop the spread of droplets from coughs or sneezes. Researchers at Florida Atlantic University tested four types of masks: a bandana, a folded handkerchief, a cone mask and a homemade cotton mask. CNBC’s Andrea Day reports on their findings.
Currently in Montreal, masks are only mandatory in one suburb, Cote-Saint-Luc, where the rule went into effect last week. They will become mandatory on public transit on July 13, though there will then be a two-week grace period, and enforcement will also begin July 27.
Other Canadian cities have also moved recently to make masks mandatory, though with shorter delays. On Monday, the City of Ottawa announced that masks will be required as of 12:01 a.m. Tuesday, just a few hours later.
Toronto announced on June 30 that it was giving about a week's notice before masks would become mandatory starting July 7, the same day as Ottawa.
