Could much of eastern Ontario become a dark-sky preserve? One group hopes so

Two ambitious visionaries are embarking on a significant project to transform a large portion of eastern Ontario into a dark-sky preserve. Embracing the concept of astrotourism, they believe that this endeavor aligns with the growing trend of people seeking solace in nature and the night sky, a trend that has been on the rise since the onset of the pandemic.

Dark-sky preserves are designated areas that prioritize reducing light pollution to safeguard the nocturnal environment for animals, insects, and plants that rely on the darkness. Astrotourism, in turn, involves individuals traveling to these preserves to witness celestial objects that are typically obscured by urban light pollution.

John Criswick, the driving force behind the NWNC Dark-Sky Project (Narrows Lock, Westport, Newboro, and Chaffeys Lock), sees this initiative as a form of “covert environmentalism” that benefits not only people but also the wilderness and its inhabitants. By seeking certification from Dark Sky International, Criswick aims to draw international attention to their efforts, distinguishing their preserve from others certified by the Royal Astronomical Society of Canada.

Their current focus is on establishing a dark-sky preserve in a smaller region, but the long-term goal is to expand this initiative to encompass a vast area spanning approximately 42,000 square kilometers. Encompassing 75 towns and townships with over half a million residents, this proposed preserve would be one of the largest in Canada, stretching from Cornwall to Hawkesbury, Petawawa, Algonquin Provincial Park, and along Highway 401, excluding larger municipalities.

One of the primary challenges they face is combatting light pollution, a pervasive issue exacerbated by the prevalence of LED lights emitting bright white and blue light. Bernie Hasselman, part of the light pollution abatement committee with the Royal Astronomical Society of Canada, highlights the detrimental effects of light pollution on human health and the environment, noting that the world loses approximately two percent of its night sky to artificial light each year.

To address this issue, Criswick and his partner Dustin Johnston emphasize the importance of educating communities about light pollution and promoting simple adjustments to reduce its impact. By encouraging the use of shielded, downward-facing, and dimmer lights with an amber spectrum, they hope to foster a greater appreciation for the natural darkness of the night sky.

As they work towards designating eastern Ontario as a dark-sky preserve, Criswick and Johnston plan to host a “dark week” in May 2026, coinciding with the 200th anniversary of the Rideau Canal’s construction. This event aims to raise awareness about the region’s pristine beauty and the importance of preserving its dark skies for future generations.

In their commitment to environmental stewardship and astrotourism, Criswick and Johnston are organizing a festival in Perth, Ont., showcasing the beauty and wonder of the night sky. Their efforts underscore the significance of protecting our natural environment and promoting sustainable practices to preserve the night sky for all to enjoy.
