The Impact of Environmental Injustice on Indigenous Communities

Historical Context of Environmental Injustice

Environmental injustice in Canada is deeply rooted in colonial histories that exclude Indigenous voices. Policies such as forced relocations and the establishment of residential schools entrenched systemic inequities, disrupting traditional practices and weakening community ties (National Inquiry into Missing and Murdered Indigenous Women and Girls, 2019). Colonial policies, including the Indian Act, fundamentally disrupted traditional land stewardship practices by enforcing systems of land ownership and governance that prioritized extractive industries and resource exploitation over Indigenous sovereignty and self-determination (Hanrahan, 2017). These policies not only dispossessed Indigenous communities of their ancestral lands but also eroded traditional knowledge systems critical to environmental sustainability. The impact of these disruptions is further compounded by inadequate infrastructure in Indigenous territories, including insufficient water systems and housing, which create systemic barriers to economic and environmental justice (Bradford et al., 2016; Indigenous Resilience Report, 2024).

Resource extraction projects, such as mining, logging, and hydroelectric developments, continue to encroach upon Indigenous lands, causing widespread environmental impacts, including deforestation, water contamination, and biodiversity loss. For example, the Mount Polley mine disaster highlighted the risks associated with poorly regulated tailings ponds (Sosa & Keenan, 2001). These projects disrupt ecosystems essential to the cultural and physical well-being of Indigenous peoples, exacerbating vulnerabilities to climate change impacts, including altered wildlife migration patterns and loss of arable land (Bunce et al., 2016; Reyes-García et al., 2024). Additionally, the lack of proper consultation with Indigenous communities violates foundational principles such as Free, Prior, and Informed Consent (FPIC), as highlighted in national frameworks (Sosa & Keenan, 2001). Violations of FPIC further marginalize Indigenous communities and exacerbate the ecological degradation of their territories. 

Recent studies document how a lack of urban tree cover and poorly maintained public infrastructure exacerbate health risks, particularly during heat waves, which are increasing in frequency due to climate change (Reyes-García et al., 2024; Fuentes et al., 2020).  For example, many remote Indigenous communities reliant on diesel generators, which are costly and environmentally harmful. Transitioning to renewable energy sources offers a viable pathway to sustainable energy sovereignty for these communities (Sarkar et al., 2015; Zambrano-Alvarado & Uyaguari-Diaz, 2024; Hanrahan, 2017). Similarly, urban heat island effects disproportionately impact Indigenous peoples living in densely populated, low-income neighborhoods with limited green spaces.These patterns underscore the urgent need for inclusive urban planning that addresses environmental justice and prioritizes green space development in historically underserved neighborhoods (Reed et al., 2024; Miller, 2021).

The cultural consequences of resource extraction are equally severe. These activities often desecrate sacred sites, interrupt ceremonial practices, and disrupt traditional ways of life. Manning et al. (2018) argue that this leads to intergenerational trauma, deepening the socio-cultural rift caused by centuries of colonial exploitation. Governance structures that prioritize industrial and governmental interests over Indigenous sovereignty perpetuate these harms, leaving Indigenous voices marginalized in policy decisions and undermining efforts for equitable resource management.

Moreover, the exclusion of Indigenous perspectives from environmental governance results in policies that inadequately address localized needs. Kemp et al. (2024) emphasize that integrating Indigenous Knowledge Systems (IKS) into decision-making processes is essential for sustainable environmental management. Hanrahan (2017) underscores that neglecting Indigenous input reinforces systemic inequities and perpetuates resource governance failures. These structural barriers highlight the urgent need for policies that incorporate Indigenous leadership and prioritize equitable partnerships to address long standing environmental injustices effectively.

Health and Social Impacts

The environmental degradation and climate challenges faced by Indigenous communities in Canada have profound health and social implications. Environmental changes, including the contamination of water supplies and disruptions to ecosystems, directly affect the physical and mental well-being of these populations. For example, pollutants from mining activities, such as mercury and arsenic, have been linked to increased rates of chronic illnesses in affected regions (Williams et al., 2018). Mercury contamination is particularly harmful, as it bioaccumulates in fish (a dietary staple for many Indigenous communities), and poses severe health risks, including neurological damage, developmental delays in children, and increased risk of cardiovascular diseases. Chronic exposure to mercury through water and traditional food sources not only impacts physical health but also leads to a cascading loss of traditional practices such as fishing, further deepening cultural disconnection and mental health challenges (Sarkar et al., 2015; Hanrahan, 2017).

Indigenous reserves experience chronic boil water advisories, a situation where communities are warned that their tap water is unsafe to drink or use without boiling it first. This reflects systemic neglect and underinvestment, as these advisories often persist for years, leaving communities without reliable access to clean drinking water (Williams et al., 2018). Water insecurity, experienced by communities such as those reliant on the Attawapiskat River, affects not only hydration and sanitation but also food security by disrupting fishing and agricultural practices (Hanrahan, 2017).

Mental health impacts are particularly acute, stemming from the erosion of cultural connections to the land and the compounded stress of environmental loss. Studies document how forced relocations due to flooding or resource extraction exacerbate rates of depression, anxiety, and substance use within Indigenous communities (Manning et al., 2018). These relocations often sever ties to ancestral lands, which are central to cultural identity and practices, contributing to intergenerational trauma.

To mitigate these health and social challenges, experts call for the integration of Indigenous health frameworks into national policies. This includes prioritizing access to culturally appropriate healthcare services, investing in preventive measures like clean water infrastructure, and addressing the mental health needs of displaced populations through trauma-informed programs (Reed et al., 2024)

Economic Impact

Indigenous economies are grounded in principles of reciprocity and sustainability, emphasizing relational stewardship of land and Indigenous economies emphasize reciprocity and sustainability, emphasizing balanced relationships with the land and resources. In stark contrast, capitalism, in tandem with colonialism, transforms land into a commodified asset, prioritizing profit over cultural and ecological significance. As Coulthard (2013) aptly observes, “Colonialism and capitalism operate hand in hand, reinforcing structures that prioritize land commodification over Indigenous governance and cultural survival.”

Indigenous communities in Canada face significant challenges in asserting control over decisions related to leasing, permitting, and licensing on their lands and waters, often encountering systemic barriers and resistance. This raises questions regarding who holds the authority to make economic decisions: e.g. resource development, infrastructure projects, and other land-use considerations (Reed et al., 2024). 

Altered ecosystems and depleted wildlife resources undermine sustainable livelihoods, such as fishing and harvesting, that are integral to Indigenous cultures and economies (Reed et al., 2024). For instance, declining salmon populations,an essential resource for many Indigenous communities, have profound economic and cultural consequences. The loss of these traditional practices disrupts intergenerational knowledge transfer and community self-determination. Impact Benefit Agreements (IBAs), designed to share revenues, frequently fail to include meaningful Indigenous participation or to address the environmental damage caused by extraction activities (Sosa & Keenan, 2001).

Intersecting Challenges

Indigenous women play vital roles as caregivers and providers, ensuring access to food, water, and shelter for their families and communities (Hanrahan, 2017). Environmental changes, such as water insecurity and land degradation, increase these responsibilities, as chronic boil water advisories disrupt access to clean drinking water and demand additional labour to ensure household health and sanitation (Williams et al., 2018; Hanrahan, 2017). This labour intensification is compounded by reduced availability of traditional food sources due to polluted waterways and disrupted ecosystems, directly impacting women’s ability to maintain traditional practices and food security (Williams et al., 2018).  Despite their pivotal roles as environmental stewards, Indigenous women frequently lack the institutional support needed to implement community-based, gender-sensitive adaptation strategies (Simms et al., 2016; Reed et al., 2024).

The health implications of environmental degradation disproportionately affect Indigenous women. Exposure to pollutants like mercury and arsenic, a common by-products of mining and industrial activities, is linked to chronic illnesses and adverse reproductive health outcomes (Sarkar et al., 2015; Williams et al., 2018). Their responsibilities often place them in direct interaction with contaminated water and food sources, exacerbating their exposure and vulnerability to health risks (Hanrahan, 2017). Moreover, the stress of environmental degradation and its cascading effects on family and community health amplify mental health challenges, including depression and anxiety, which are further compounded by heightened vulnerability to violence and exploitation in resource-dependent regions where social services are scarce (Manning et al., 2018; Fuentes et al., 2020). The influx of transient workers in resource-extraction projects exacerbates these challenges, correlating with increased incidences of gender-based violence, exploitation, and trafficking (Williams et al., 2018). These overlapping stressors highlight the intersection between environmental degradation, mental health crises, and the systemic risks of violence faced by Indigenous women and gender-diverse individuals.

Youth and elders within Indigenous communities also experience unique challenges. Youth often face displacement due to environmental disasters, which disrupt their education and social networks, compounding the long-term socioeconomic impacts on future generations (Manning et al., 2018). Elders, who are critical knowledge keepers, are particularly vulnerable to climate-related health issues and the loss of traditional lands, which diminishes their ability to pass on cultural practices and wisdom (Reed et al., 2024).

Geographic location further compounds these vulnerabilities. Remote and northern Indigenous communities frequently experience delays in receiving emergency aid during extreme weather events, as well as persistent infrastructure deficits that hinder adaptation efforts (Hanrahan, 2017). Communities reliant on traditional practices, such as hunting and fishing, face existential threats as ecosystems are degraded and wildlife patterns are altered by climate change (Williams et al., 2018).
