What does it mean to have a right to a healthy environment? And is this a right that Canadians can have and enjoy?

Having a right to a healthy environment means that the government guarantees its people access to clean air, safe water, and uncontaminated lands on which to live.[1] While the right to a healthy environment (or a similar guarantee) is now included in the constitutions of over 110 countries, Canada’s Constitution contains no such express right.[2]

What we eat, drink, and breathe

It is well known that human health is negatively impacted when the integrity of the water, air, and land that surrounds us is compromised. Air pollution causes the premature deaths of thousands of Canadians each year and contributes to health problems including heart disease, asthma, and lung cancer.[3] Pesticides that can end up in our food and on our skin are linked to cancer and damage to the human reproductive, immune, and nervous systems.[4]

Poor water quality is often a source of tragedy for Canadian communities. In the year 2000, seven people died and more than 2,300 people fell ill in Walkerton, Ontario after the town’s water supply became contaminated with deadly bacteria.[5] In the 1960s, two First Nations communities in Ontario were exposed to mercury poisoning when a nearby pulp mill began dumping toxins into the English-Wabigoon River.[6] Over 50 years later, the residents in those communities continue to suffer from the symptoms of mercury poisoning, including impaired vision, tremors, speech impairment, limb numbness, and birth defects.[7]

As of early 2017, approximately 150 drinking water advisories[8] existed in First Nations communities across Canada, with 71 of those advisories having been in place for longer than a year.[9] Two-thirds of all First Nations communities in the country have been issued at least one water advisory over the past ten years.[10]

Given that human survival depends on having access to safe water, clean air, and unpolluted lands, it is natural to ask whether Canada’s Constitution can, and indeed, should, protect those fundamental needs.

Why does constitutional protection matter?

Examples from abroad

Other countries provide some useful examples of the kind of protection a constitutional right to a healthy environment can give. In the Netherlands, the Hague District Court ordered the Dutch government to take greater action to reduce greenhouse gas emissions.[11] One important factor the Court considered was the government’s constitutional duty to protect and improve the living environment and to maintain the country in a “habitable state.”[12]

In Argentina, citizens sued the national, provincial, and local municipal governments for polluting a major river, claiming that their right to a healthy environment had been violated.[13] The Argentinian Supreme Court ordered the governments to take several specific measures to clean up the river basin and to stop further contamination.[14] The Court’s decision was made in part on the basis that Argentina’s Constitution expressly includes the right to a healthy environment.

Like Argentina, the people of the Philippines have the right to a healthy environment listed in their Constitution (specifically, the right to “balanced and healthful ecology”). On that basis, the Supreme Court of the Philippines ordered government agencies to clean up the heavily polluted Manila Bay in 2008.[15]

Constitutional strength

Why include a right to a healthy environment in the Constitution, specifically, rather than simply create laws to protect different aspects of the environment?

The Constitution is the supreme (or highest) law in Canada, which means that all other laws and government actions must comply with the Constitution.[16] Entrenching a right to a healthy environment in the Constitution would therefore allow people to hold the government accountable for laws and government actions that violate that right.[17]

A constitutional right to a healthy environment would also help stop a newly formed government from removing laws that a previous government created to protect the environment.[18] This is because the Constitution is harder to change (or “amend”) than other laws.[19] With a constitutional right to a healthy environment, a basic, minimal level of protection for the water, air, and land is therefore better able to survive changes to the governing political party.

How can the right to a healthy environment become a constitutional guarantee?

The right to a healthy environment is not expressly listed in the Canadian Charter of Rights and Freedoms.[20] So how does such a right become a guarantee that all Canadians can rely upon?

The first way that the right to a healthy environment can become a recognized protection in the Constitution is for the federal government, backed by provincial support, to expressly add that right to the Charter.[21] This would involve a direct amendment to the Charter, which requires that the federal government have the support of two-thirds of the provinces representing at least 50% of Canada’s population (referred to as the “general amending formula,” found in section 38 of the Constitution Act, 1982).[22] Such an approach is difficult because of the level of consensus it requires between the federal government and a large number of provinces who often have very different priorities.[23] Over the past 35 years, the general amending formula has successfully been used to change the Constitution only once in 1983 when a section was added to clarify the effect of the Charter on Aboriginal rights.[24]

The second route to creating a right to a healthy environment is for a court to find that the right is implicitly included within the existing Charter rights. For example, a court can conclude that section 7 of the Charter, which guarantees the right to life, liberty, and security of the person, includes a right to have access to things like safe drinking water, air above a specific quality standard, and/or uncontaminated lands on which to live.[25]There are two paths available that can lead to such a court finding:

  1. A judicial reference. The federal or provincial governments can ask the courts whether a specific section of the Charter, such as section 7, includes an implied right to live in a healthy environment.[26] This process of the government asking for advice from the courts is called a judicial reference, and has been used frequently through Canada’s history.[27]
  2. Private litigation against the government. Individuals living in Canada can claim that a government action or law that causes a specific harm to the environment (like water contamination or air pollution) violates their right to life, liberty, and security of the person in section 7 of the Charter.[28] Notably, it could be argued that certain types or locations of environmental degradation could violate section 2(a) religious freedoms or section 15 equality rights, but section 7 is recognized as the right most likely to include an implied guarantee to a healthy environment.[29] If a court finds that a government action or law that causes harm to the environment violates section 7, then a right to a healthy environment (or a right to something simpler such as access to safe drinking water) would be recognized as being guaranteed by the Charter.

Finding the right to a healthy environment in section 7

Section 7 of the Charter guarantees everyone in Canada “the right to life, liberty and security of the person and the right not to be deprived thereof except in accordance with the principles of fundamental justice.”

In certain circumstances, a court could find that a person is deprived of their life, liberty, and/or security interests by government actions or laws that damage the environment. For example, a law or government action may deprive an individual of their right to life if it leads to increased air, water, or soil contamination that causes premature death.[30] Similarly, Canadians may be deprived of their right to security of the person when a government decision results in an environmental catastrophe that causes people “physical or serious psychological suffering.”[31]

Liberty interests may be engaged where a government gives its approval for new polluting activities that cause members of a community to suffer from cancer, birth defects, and fear of venturing outside of their homes.[32] Such a decision made by the government can restrict an individual’s ability to make fundamental personal choices regarding where they live and how they can meet their basic needs.[33]

Of note is that no Canadian court has yet found that government inaction can violate section 7 of the Charter.[34] This is especially relevant when considering the right to a healthy environment because a government’s inaction, such as failing to monitor water quality, not limiting greenhouse gas emissions, or refusing to clean up a contaminated ecosystem will impact the health of the environment.

Up to the current time, courts have found only that laws and government actions are required to comply with the Charter.[35] As stated by the Supreme Court of Canada in Chaoulli v Quebec (AG), this means, for example, that the Charter does not place a positive obligation on the government to actively provide Canadians with a service such as health care.[36] The requirement is that if the government decides to provide health care, it must do so in a way that complies with Charter rights.[37] However, the Supreme Court has also said that in the future, it is possible that “a positive obligation to sustain life, liberty, or security of the person may be made out in special circumstances.”[38]

While the Supreme Court has not recognized the existence of a right to a healthy environment in the Charter, the Court has called environmental protection “a fundamental value in Canadian society.”[39] The Supreme Court has also expressed that “our common future, that of every Canadian community, depends on a healthy environment.”[40]

Are we moving toward a right to a healthy environment?

Despite interest in including a right to a healthy environment in the Constitution leading up to, and after the creation of the Charter, that right never became an express constitutional guarantee.[41] Since 2009, Linda Duncan – Member of Parliament for Edmonton-Strathcona – has proposed several times that Parliament pass a Canadian Environmental Bill of Rights.[42] Most recently, Duncan re-tabled her private member’s bill, Bill C-202, in December 2015, and it currently remains in the early stages of consideration. Although the Bill would lack constitutional status and only restrict federal laws and the actions of the federal government, it would mark a significant step towards recognizing a right to a healthy environment.[43]

In 2010, members of the Aamjiwnaang First Nation filed a lawsuit against Ontario’s provincial government, claiming that their section 7 rights had been violated.[44] The government had approved of additional industrial activity near the First Nation community, which is located in a valley already known for its high levels of air pollution. The lawsuit was withdrawn in the summer of 2016 as the Ontario government began to correct several of the problems that triggered the lawsuit.[45] As a result, no finding was made in court on the section 7 issue.

Meanwhile, Canadians continue to face threats from a changing climate and pollution from a multitude of sources.[46] Until future court cases, a judicial reference, or a direct amendment result in turning the right to a healthy environment into a constitutional guarantee, that right remains more phantom than reality.

[29] Ibid. It could be argued that the section 15 equality rights of Aboriginal peoples are engaged by government actions or laws that result in air or water pollution because of the differential adverse impacts that such pollution has on historically disadvantaged First Nations communities. The differential adverse effects arise because of the close physical and cultural connections that First Nations people have to their lands and the fact that First Nations reserves are often located near sites of industrial pollution. See Lockridge v Ontario (Ministry of Environment) (10 January 2012), Toronto, Ont Sup Ct 528-10 (amended notice of application) at 15-16 [Lockridge Application]. The section 2(a) guarantee to freedom of conscience and religion may also be engaged in the case of some First Nations peoples living in Canada. Aboriginal peoples who hold sincere beliefs related to the integrity of the natural environment and who rely on wildlife or undisturbed ecosystems in order to practice their beliefs can argue that their freedoms are violated when government intervention causes environmental harm.
