La présentation aborde une étude et une analyse approfondie de la littérature qui visent à déterminer les moments les plus critiques pour minimiser les impacts sur la santé lors d'une évacuation due aux feux de forêt. Pour ce faire, douze intervenants d'une région socio-sanitaire touchée par les incendies ont été interrogés au moyen d'entrevues semi-dirigées. L'analyse de ces entrevues a permis de mettre en évidence des moments charnières ayant un impact significatif, positif ou négatif, sur la santé. Ces quatre moments clés, comprenant la communication de l’ordre d'évacuation, le transport adapté, l'hébergement durant les évacuations et la phase de rétablissement, se révèlent être ceux nécessitant une attention particulière. Les résultats de cette étude exploratoire ont été confrontés à ceux d'une analyse thématique portant sur les mêmes sujets. La présentation proposera ainsi une réflexion critique sur les défis, les impacts sur la santé et les…
Le CCNSE offre régulièrement des présentations dans le cadre d’activités liées au secteur de la santé environnementale tenues partout au Canada, et il organise des ateliers ainsi que des réunions sur divers sujets. Vous trouverez ici une liste de certaines présentations faites dans le cadre de conférences et de webinaires d’organismes externes, en plus de présentations tirées de notre Série de séminaires sur la santé environnementale.
[Le webinaire est présenté en anglais]
Les épisodes de chaleur extrême se multiplient au Canada et l’on prévoit qu’ils ne cesseront d’augmenter, non seulement en intensité et en durée, mais aussi en étendue géographique. Il faut donc redoubler d’efforts pour se préparer à ces épisodes, car les menaces que fait peser la chaleur extrême sur les personnes, les communautés et les systèmes de santé s’affirment à mesure que le réchauffement s’accentue. Les communautés qui ne sont pas présentement exposées à ces épisodes pourraient également y être confrontées dans le futur. Afin d’aider les autorités de santé publique à comprendre de quelle manière la situation peut évoluer, cette séance expliquera comment utiliser le portail Web Donneesclimatiques.ca pour explorer les prévisions d’épisode de chaleur extrême. Nous présenterons également les dernières prévisions de l’indice humidex et aborderons les défis que pose la communication des risques liés à la chaleur extrême de…
Face à l’aggravation des vagues de chaleur, des conditions météorologiques typiques, des pannes d’électricité, de la chaleur urbaine, et d’autres facteurs, comment pouvons-nous adapter nos bâtiments afin qu’ils puissent nous abriter jusqu’à la fin de leur cycle de vie? Afin de tirer parti des avantages connexes pour la santé et la productivité tout en limitant les responsabilités, il faut placer la résilience et l’adaptation climatiques au cœur des efforts déployés pour réduire la consommation d’énergie, construire des bâtiments sains et assurer la décarbonation des bâtiments. Cette présentation résumera les risques que représentent les changements climatiques et la surchauffe des bâtiments pour la santé, ainsi que les différentes lignes directrices et normes d’aménagement conçues pour limiter la surchauffe des bâtiments. Elle donnera également plusieurs exemples illustrant la manière dont des bâtiments adaptés aux changements climatiques et à faible risque de surchauffe peuvent…
This presentation is based on an NCCEH Evidence Review titled Growing at home: Health and safety concerns for personal cannabis cultivation, which you can access here. A two page factsheet was also developed which is available here.
Multiple versions of this presentation were given between May 2018 and March 2019 to various stakeholder groups including: CIPHI National, CIPHI Manitoba, CIPHI Ontario, First Nations Health Authority (Environmental Public Health Services), First Nations and Inuit Health Branch, Nova Scotia Health Authority, Alberta Health Services (Safe Healthy Environments), BC Lung, the Canadian Public Health Association, and UBC’s School of Population and Public Health. While individual presentations were tailored to each group, this slide deck has been developed to represent a generalized version that contains the key content presented to each group.
Images of communities and homes destroyed or damaged following extreme weather events are increasingly familiar. But after the cameras leave, a less visible, longer-term toll can settle in on the mental and physical well-being of those who have suffered great loss. That suffering can linger for years. This talk will quantify these often less considered impacts that follow in the aftermath of large scale flooding, with results that are equally applicable to forest fire-related loss. On the upside, much work has been done over the past few years to prepare for extreme weather. Accordingly, the discussion will end by highlighting practical and cost-effective actions that can be taken today, to avoid suffering tomorrow.

CO2 monitoring is an established tool to assess occupancy and ventilation requirements for indoor spaces, typically for the purposes of increasing energy efficiency. During the pandemic, it is critical that spaces are adequately ventilated for the number of occupants and type of activities, but it is often unclear if ventilation objectives are being met. CO2 monitoring can help to address ventilation inadequacy, provided that users are able to install, monitor, interpret, and react to these devices. However, there are a number of technical and risk communication challenges regarding CO2 monitoring by non-expert occupants, including the tendency to misinterpret CO2 as a direct indicator of COVID-19 risk. This webinar will review some of the public health commentary or guidance on CO2 monitoring during the pandemic, and will identify the more challenging aspects of this practice to help facilitate decision-making and communication around CO2 sensors.
Canada is entering unchartered territory as it regularly experiences record high temperatures. It is predicted that this trend will continue and periods of extreme heat in Canada will be more frequent, intensify, and likely to be five times more deadly within the next few decades. However, our understanding of the effectiveness of commonly recommended heat-mitigation strategies to protect vulnerable Canadians and Canadian workers remains incomplete, limiting our ability to make evidence-based decisions on the best strategies to implement.
We showed that the body’s response to heat is impaired in healthy adults as young as 40 years. This impairment is worse in older adults and in those with common chronic disease such as diabetes and hypertension. In these individuals, heat tolerance is reduced as the body is unable to cool itself via the evaporation of sweat, placing them at increased risk of heat-induced illnesses or death.
Given that Canada’s population and…
The effects of climate on the environment and human health impacts have been increasingly observed with some negative health outcomes shown through mortality and hospitalization data. Warning systems are put in place by public health authorities to intervene during episodes of extreme weather events. In Quebec, the SUPREME system that was developed by the Institut National de Sante Publique du Quebec (INSPQ) has been used for a decade to document relevant and real-time information for Quebec’s extreme weather hazards and their associated heat and all-cause mortality. However, other extreme events such as cold in Nordic regions or air pollution in large cities are also important to study. It is therefore important to adapt this system using appropriate methodologies so it can be applicable to specific health impacts that may be linked to other extreme weather hazards. In this presentation, Dr. Fateh Chebana will focus on cold-mortality and hospitalisation data in Quebec, as well as…
Urban areas are the hot spots of global warming. Extreme heat, alongside flooding and wildfire, is a key risk to the health and well-being of Canadians. The situation is growing more dangerous, driven by irreversible climate change— Canada is warming, on average, at twice the global rate.
Urgent action is required now to manage risk and avoid worsening impacts – and ultimately fatalities.
The good news is that heat-related illness and death are largely preventable with knowledge, education, and adaptive action. However, resilience to extreme heat cannot be achieved by relying on air conditioning alone.
This presentation will provide an overview of new national guidance, representing input from over 60 subject matter experts, outlining practical actions that Canadians can undertake to reduce risks from extreme heat including:
changing behaviour (non-structural) working with nature (green infrastructure) improving buildings and public infrastructure (…
