Canadian municipalities are taking action to prevent the sale of invasive plants in local garden centers, advocating for a national strategy to regulate the horticultural industry. Invasive plants pose a threat to biodiversity nationwide, prompting local governments to address gaps in the current regulatory framework that varies by region. Canada aims to reduce the introduction and establishment of invasive species by at least 50% by 2030.
The Canadian Coalition for Invasive Plant Regulation (CCIPR) is urging the federal government to establish a regulatory body for the horticultural sector and develop a national database identifying invasive plants and associated risks in different areas. CCIPR co-founder Cathy Kavassalis emphasized the importance of informing the public about potentially harmful plants, similar to regulations on 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’s approach focuses on species-specific risks rather than a blanket prohibition on all invasive plants in every region.
Recent municipal actions include Nanaimo and Surrey passing motions to restrict the sale of invasive plants listed by the Invasive Species Council of B.C. and London recommending retailers provide information on invasive plants at the point of sale. Kavassalis highlighted the need for a comprehensive federal approach instead of fragmented municipal solutions.
Advocates stress the need for a national database to inform stakeholders about regional risks posed by invasive plants. Jim Hole, a horticulture expert, stated that most garden centers support preventing the spread of invasive species and are willing to adjust their inventory accordingly. Native plant advocate Lorraine Johnson emphasized the industry’s influence on biodiversity loss and the importance of educating consumers about choosing non-invasive plants for their gardens.
Efforts to regulate garden centers can enhance public awareness and combat “plant blindness,” encouraging a deeper connection between gardeners and the broader ecosystem. The push for federal action aligns with the target set to reduce the impact of invasive species by 2030, emphasizing the shared responsibility among different levels of government, industry, and organizations in managing invasive plants effectively.
