MONTREAL -- Montrealers are heading outdoors to enjoy the spring weather, but confusion remains over which of the activities they're engaging in require masks. On Saturday, many people headed to the city's parks, glad for a chance to socialize, albeit with physical distancing, after a lonely winter. “The nice weather is here, so we're trying to see our friends slowly in small groups outdoors, trying to stay sane,” said one park-goer. But when meeting those friends from other households, a mask is required if people are not standing two metres apart at all times. While the science has shown that COVID-19 does not travel well outdoors, epidemiologist and cardiologist Chris Labos warned that the risk is not zero.
