Climate wasn't a specific factor listed within the legislation of the Canadian Environmental Assessment Act, 2012, but in 2016 the government put policy guidelines in place that would require the agency to look at climate impacts for projects that were underway throughout that framework.
In the case of Teck Frontier, the panel did look at impacts of climate change throughout that assessment, and it's more specifically laid out as a specific criterion under the new Impact Assessment Act for any new projects that will be coming forward under that legislation.
