This legislation also outlawed the use of lead in gasoline and the use of substances that are harmful to the atmosphere, and required new chemical substances to be inspected to determine whether those chemicals could be put to use without harming the environment. Subsequently, the Canadian Environmental Protection Act caused the examination of approximately 23,000 substances that were introduced to Canada before the country had strong environmental legislation in 2006. This is known as the Categorization, because the chemicals inspected were classified into two groups; safe for the environment, meaning they could be used, and harmful to the environment, which made the use of those chemicals prohibited. The Canadian Environmental Protection Act is a crucial aspect of Canada’s environmental legislation because many regulations were introduced for the betterment of the environment and the health of Canadians. The implementation of these laws combatted a broad range of environmental issues, ultimately promoting environmentalism for the sake of human health and wellbeing, which caused Canadians to care more about ecological footprints and the environment as a whole. In conclusion, Canada has demonstrated environmentalism through reducing the impacts of human-induced pollution, conserving and protecting wildlife, and put laws in place to further improve the country’s environment. Environmentalism in Canada has improved drastically since the 1960s through setting goals and legislation for the betterment of Canada. Canada’s environmental efforts made environmentalism widespread in the country. Canadians reduced pollution through taking part in international conferences about the topic, conserved nature through forming organizations, and implemented many laws to combat a variety of climate change issues for the purpose Canada’s residents to have lighter ecological footprints.A way the environmentalism continues to popularize in Canada is through international treaties. Starting in 2012, when Canada’s prime minister (P.M.) was Stephen Harper, the country adopted a more “economy over environment” attitude after the P.M. backed out of the Kyoto Accord, calling it the “. . . job-killing, economy-crushing Kyoto Accord” in a Canadian Alliance fundraising letter, and believed the agreement was causing Canada to fall behind economically. However, in October 2015, when Justin Trudeau was elected prime minister, he focused greatly on climate change once he took office. Parliament voted to ratify the Paris Agreement on October 5th, 2016, one year after he took office. Justin Trudeau stated: “We are all custodians of this world, and that is why Canada will continue to to address climate change and promote clean growth”, proving Canada was taking a leap in the right direction, by improving mistakes made in the past under the rule of the new Prime Minister. The Government of Canada is committed to reducing 30% reduction in greenhouse gas emissions from 2005 levels by 2030 as a result of the agreement, bringing forth a new streak of environmental activism after it was broken through the Kyoto Accord. The fact that Canadians have been striving to help out and undo the mistakes they have made shows a desire for improvement, which is crucial in a world facing many environmental issues.
