The Right to a Healthy Environment (and more) in the Canadian Environmental Protection Act: A First for Canadians

"...As a refresher, the Canadian Environmental Protection Act (“CEPA”) is the federal law that manages and regulates prescribed types of pollution. Generally, CEPA sets out the obligations of Environment and Climate Change Canada and Health Canada “related to the assessment and management of risks from chemicals, polymers and living organisms; programs related to air and water pollution, hazardous waste, air pollutant and GHG emissions; ocean disposal; and environmental emergencies. ”[3] CEPA declares that the Government of Canada “is committed to implementing pollution prevention as a national goal and as the priority approach to environmental protection..."

New emissions targets may sink LNG’s pitch as a shipping fuel

"...The new accounting method means LNG can no longer sail under the radar when it comes to emissions, said Elissama Menezes, global campaign director for the Say No to LNG coalition. “It’s a huge step and quite exciting to see,” Menezes told Canada’s National Observer. What people are reading Canada’s Conservatives are courting constitutional chaos By Max Fawcett | Opinion, Politics | July 11th 2023 “At the end of the day, it really brings some accountability to the shipping sector, which for too many years has not really been responsible for the whole footprint of its emissions..."

Montreal fireworks cancelled over wildfire smoke

"...Dr. David Kaiser, deputy medical director of Montreal's public health department, said a 2022 report on the city's air quality indicated that fireworks displays can lead to concentrations of air pollutants — known as fine particulate matter — of 300 particles per cubic metre, a level considered very unhealthy. "There is a measurable impact that lasts for a few hours and that touches mostly the neighbourhoods that are surrounding the fireworks show," he told reporters alongside Émond, adding that those areas have some of the worst air quality in the city at normal times, due to vehicle traffic and industrial sites..."
