Canadian cities are taking steps to prevent the sale of invasive plants in local garden centers, as advocates urge the Canadian government to implement a nationwide approach to regulate the horticultural industry. Invasive plants pose a threat to biodiversity nationwide, prompting municipalities to address gaps in the current regulatory framework that varies by region. Canada has committed to reducing the introduction and establishment of known invasive species by at least 50% by 2030.
The Canadian Coalition for Invasive Plant Regulation (CCIPR) is calling on the federal government to establish a regulatory body for the horticultural sector and develop a national database cataloging invasive plants and associated risks in different areas. CCIPR co-founder Cathy Kavassalis emphasized the need to inform the public about potential harms posed by invasive plants, similar to how warnings are provided for other products.
While the Canadian Food Inspection Agency (CFIA) oversees some invasive plants under the Plant Protection Act, provinces and territories have their own legislation on invasive species and weed control. The CFIA highlighted that their approach focuses on species-specific risks rather than a blanket ban on all invasive plants, restricting the import, sale, and movement of regulated pest plants.
Recent actions by local governments reflect the growing concern over invasive plants. Nanaimo and Surrey have moved to restrict the sale of invasive plants, and London’s environmental committee proposed requiring retailers to provide information on invasive plants and animals at the point of sale. Advocates stress the importance of a cohesive national strategy to address the issue effectively.
Experts emphasize the role of nurseries in preventing the spread of invasive plants, with horticulture specialist Jim Hole highlighting the industry’s support for such initiatives. Efforts to educate the public, enhance regulation, and conduct research are seen as crucial in safeguarding biodiversity and ecosystems from the threats posed by invasive species.
Advocates are calling for the establishment of a national database to facilitate information-sharing on invasive plants, aiding provinces, retailers, and gardeners in identifying and managing risks. The horticultural industry’s influence on consumer choices and biodiversity loss underscores the need for greater awareness and regulation to mitigate the impact of invasive species on the environment.
