Guided by Science

Make least-toxic the norm. Counter vested interests that thwart health.

Action Agenda

Major farming groups and experts agree that substantial pesticide reduction and adoption of organic practices are essential for Sustainable Agriculture and food security. See PCN’s federal submission, and ask your MP to support truly sustainable agriculture.

THANK YOU for taking action! Municipalities across Canada have a concerning number of old asbestos cement water supply pipes that can contaminate drinking water. Public response means that this petition is certified — the Federal Government must publicly respond to citizens’ request that it take immediate steps to assess and act on the health risks.

Mar. 23, 2023 / A major peer-reviewed publication reports that many aspects of child development can be affected by radiofrequency “wireless” radiation, and screen time.

Leading international scientists find impacts on bonding, speech acquisition, behaviour, socialization, learning and addictions. Cancer risks are also increased.

Recommendations include use of wired technologies, that wireless radiation exposures be “ALARA” (as low as reasonably achievable), that physicians query use of tech in well-child visits, and research to prevent and investigate electrohypersensitivity.

Canadian Forces Base Gagetown Fact-Finding Project reports re: herbicide spraying, 1952–2004

As well, during the Cold War (1966 and 1967), the United States tested herbicides in small strips of northern forest on the base. Herbicide trials included Agent Orange and other “Rainbow Herbicides“ that became infamous during the Vietnam War. Members of the military and their families have been affected by these herbicides and associated…

Glyphosate and leukemia

Global Glyphosate Study leukemia results show leukemia in early adulthood when leukemia is very rare. The results align, however, with increasing leukemia in U.S., ages 15-39, since early 1990s. The picture is painted in four studies.

Nuclear waste storage undermined by climate change

Optimistic future rainfall estimates risk containment of radioactive and toxic chemicals. The NSDF risks polluting the local ecosystem and foods, and drinking water for millions of people downstream along the Ottawa River.

The Futility of Carbon Capture and Storage

Federal tax dollars for Carbon Capture and Storage are a direct subsidy to a very profitable but toxic fossil fuel industry. The Canadian government’s billions for this unproven technology provides a delay for fossil fuels carbon emissions to continue unabated through 2050.
