To ease food insecurities in northern Canada, some remote communities started gardening initiatives to gain more access to locally grown foods. Bush beans (Phaseolus vulgaris L.) and potatoes (Solanum tuberosum L.) were assessed for N, P, K, Mg, and Ca concentrations of foliage as indicators of plant nutrition in a calcareous silty loam soil of northern Ontario James Bay lowlands. Crops were grown in sole cropping and intercropping configurations, with comparisons made between an open field and an agroforestry site enclosed with willow (Salix spp.) trees. Foliage chemical analysis of the sites revealed an abundance of Ca, adequacies for Mg and N, and deficiencies in P and K. Intercropping bean and potato did not show significant crop–crop facilitation for nutrients. The agroforestry site showed to be a superior management practice for the James Bay lowland region, specifically for P. The agroforestry site had significantly greater P for bean plant (p = 0.024) and potato foliage (p = 0.002) compared to the open site. It is suspected that the presence of willows improve plant available P to bean and potatoes by tree root—crop root interactions and microclimate enhancements.

Aboriginal people in Canada experience disproportionately high rates of diet-related illnesses, such as obesity and diabetes. Food insecurity has been identified as a contributing factor to these illnesses along with a loss of traditional lifestyle. Current food systems within northern subarctic and arctic regions of Canada rely heavily on imported foods that are expensive (when available), and are environmentally unsustainable. A warming subarctic and arctic climate present challenges, but also offers the opportunity for local agricultural production that can increase food security and promote a more sustainable food system. In this study the feasibility of sustainably growing potatoes (Solanum tuberosum L.) utilizing agroforestry practices to enhance food security in remote subarctic communities is explored through a case study in Fort Albany First Nation in northern Ontario, Canada. Potato crops were grown over a two-year period and rotated into plots that had been planted with green bush beans (Phaseolus vulgaris L.). Results showed that potatoes and bush beans could be grown successfully in the subarctic without the use of greenhouses with yields comparable to more conventional high-input agricultural methods. In subarctic Canada, sustainable local food production can help to promote social capital, healthier lifestyles, and food security.

This study will compare Canadian and Australian case studies to glean insights and compile lessons learned to better understand how resource development should occur in a way that fosters Indigenous peoples' cultural wellbeing in the present and the future. Both Indigenous populations experienced the institutional effects of European settler state policies, which subsequently engendered forms of social and political colonialism, and both Indigenous populations have had similar experiences with transnational mining companies encroaching on traditional lands as part of a broader process of globalization. We contend that we need a fundamentally different approach to resource development that affects Indigenous traditional lands in both Ontario, Canada, and NSW, Australia; one that takes into consideration the core values needed to sustain Indigenous cultural wellbeing in the present and the future.

There is concern of avian influenza virus (AIV) infections in humans. Subsistence hunters may be a potential risk group for AIV infections as they frequently come into close contact with wild birds and the aquatic habitats of birds while harvesting. This study aimed to examine if knowledge and risk perception of avian influenza influenced the use of protective measures and attitudes about hunting influenza-infected birds among subsistence hunters. Using a community-based participatory research approach, a cross-sectional survey was conducted with current subsistence hunters (n = 106) residing in a remote and isolated First Nations community in northern Ontario, Canada from November 10-25, 2013. Simple descriptive statistics, cross-tabulations, and analysis of variance (ANOVA) were used to examine the distributions and relationships between variables. Written responses were deductively analyzed. ANOVA showed that males hunted significantly more birds per year than did females (F1,96 = 12.1; p = 0.001) and that those who hunted significantly more days per year did not perceive a risk of AIV infection (F1,94 = 4.4; p = 0.040). Hunters engaged in bird harvesting practices that could expose them to AIVs, namely by cleaning, plucking, and gutting birds and having direct contact with water. It was reported that 18 (17.0%) hunters wore gloves and 2 (1.9%) hunters wore goggles while processing birds. The majority of hunters washed their hands (n = 105; 99.1%) and sanitized their equipment (n = 69; 65.1%) after processing birds. More than half of the participants reported being aware of avian influenza, while almost one third perceived a risk of AIV infection while harvesting birds. Participants aware of avian influenza were more likely to perceive a risk of AIV infection while harvesting birds. Our results suggest that knowledge positively influenced the use of a recommended protective measure. Regarding attitudes, the frequency of participants who would cease harvesting birds was highest if avian influenza was detected in regional birds (n = 55; 51.9%). Our study indicated a need for more education about avian influenza and precautionary behaviours that are culturally-appropriate. First Nations subsistence hunters should be considered an avian influenza risk group and have associated special considerations included in future influenza pandemic plans.

Influenza pandemics disproportionately impact remote and/or isolated Indigenous communities worldwide. The differential risk experienced by such communities warrants the recommendation of specific mitigation measures. Interviewer-administered questionnaires were conducted with adult key health care informants from three remote and isolated Canadian First Nations communities of sub-Arctic Ontario. Forty-eight mitigation measures (including the setting, pandemic period, trigger, and duration) were questioned. Participants’ responses were summarized and collected data were deductively and inductively coded. The participants recommended 41 of the questioned mitigation measures, and often differed from previous literature and national recommendations. Results revealed that barriers, such as overcrowded housing, limited supplies, and health care infrastructure, impacted the feasibility of implementing mitigation measures. These findings suggest that pandemic plans should recommend control strategies for remote and isolated Canadian First Nations communities that may not be supported in other communities. These findings highlight the importance of engaging locally impacted populations using participatory approaches in policy decision-making processes. Other countries with remote and/or isolated Indigenous communities are encouraged to include recommendations for mitigation measures that specifically address the unique needs of such communities in an effort to improve their health outcomes during the next influenza pandemic.

In Canada, the use of omnibus budget bills in recent years has grown substantially. In 2012, it was used twice by the Government of Canada. As a result, a number of substantial changes to environmental legislation were introduced with virtually no debate nor compromise. This situation has been criticized for seriously reducing the credibility of the budget process and the authority of Parliament in Canada, as well as undermining the transparency and accountability of the policy-making process. This paper describes how changes to major policies through the use of omnibus bills (all, arguably, in the name of faster project review decisions) affect not only established environmental protection efforts, but also the public and Aboriginal (First Nations, Inuit and Metis) peoples, particularly in terms of their capacity to effectively participate in resource development.
