The impacts of the Nutrition North Canada program on the accessibility and affordability of perishable, nutritious foods among eligible communities: a scoping review.

The Nutrition North Canada (NNC) program, introduced in April 2011 is a federal strategy to improve access to perishable, nutritious foods for remote and isolated communities in northern Canada by subsidising retailers to provide price reductions at the point of purchase. As of March 2023, 123 communities are eligible for the program. To evaluate existing evidence and research on the NNC program to inform policy decisions to improve the effectiveness of NNC. A scoping review of peer-reviewed articles was conducted in ten databases along with a supplemental grey literature search of government and non-government reports published between 2011 and 2022. The search yielded 172 publications for screening, of which 42 were included in the analysis. Narrative thematic evidence synthesis yielded 104 critiques and 341 recommendations of the NNC program across eight themes. The most-identified recommendations focus on transparency, communication, and support for harvesting, hunting, and community food initiatives. This review highlights recommendations informed by the literature to address critiques of the NNC program to improve food security, increase access to perishable and non-perishable items, and support community-based food initiatives among eligible communities. The review also identifies priority areas for future policy directions such as additional support for education initiatives, communication and transparency amidst program changes, and food price regulations.

Public policy interventions to mitigate household food insecurity in Canada: a systematic review.

OBJECTIVE: The objective of this systematic review is to synthesise the evidence on public policy interventions and their ability to reduce household food insecurity (HFI) in Canada. DESIGN: Four databases were searched up to October 2023. Only studies that reported on public policy interventions that might reduce HFI were included, regardless of whether that was the primary purpose of the study. Title and abstract screening, full-text screening, data extraction, risk of bias and certainty of the evidence assessments were conducted by two reviewers. RESULTS: Seventeen relevant studies covering three intervention categories were included: income supplementation, housing assistance programmes and food retailer subsidies. Income supplementation had a positive effect on reducing HFI with a moderate to high level of certainty. Housing assistance programmes and food retailer studies may have little to no effect on HFI; however, there is low certainty in the evidence that could change as evidence emerges. CONCLUSION: The evidence suggests that income supplementation likely reduces HFI for low-income Canadians. Many questions remain in terms of how to optimise this intervention and additional high-quality studies are still needed.

Sources of exposure to lead in Arctic and subarctic regions: a scoping review.

Understanding lead exposure pathways is a priority because of its ubiquitous presence in the environment as well as the potential health risks. We aimed to identify potential lead sources and pathways of lead exposure, including long-range transport, and the magnitude of exposure in Arctic and subarctic communities. A scoping review strategy and screening approach was used to search literature from January 2000 to December 2020. A total of 228 academic and grey literature references were synthesised. The majority of these studies (54%) were from Canada. Indigenous people in Arctic and subarctic communities in Canada had higher levels of lead than the rest of Canada. The majority of studies in all Arctic countries reported at least some individuals above the level of concern. Lead levels were influenced by a number of factors including using lead ammunition to harvest traditional food and living in close proximity to mines. Lead levels in water, soil, and sediment were generally low. Literature showed the possibility of long-range transport via migratory birds. Household lead sources included lead-based paint, dust, or tap water. This literature review will help to inform management strategies for communities, researchers, and governments, with the aim of decreasing lead exposure in northern regions.
