Supplied. Ontario’s Regional Chief is raising some big concerns over climate change and how it is affecting First Nations communities in Northern Ontario. Isadore Day says Indigenous people are the first to feel the affects of global warming, and he is asking the province and the federal governments to order a climate change impact study. He says the main concern is the length of time ice roads are open. The season has been dramatically reduced; causing food, fuel, and medical supply shortages. He says the winter roads used to be open for 50 to 60 days, and now they are looking at only 20.
