Canadian municipalities are taking action to prevent the sale of invasive plants in local garden centers, while urging the Canadian government to implement a nationwide strategy for regulating the horticultural trade. 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 50% by 2030.
The Canadian Coalition for Invasive Plant Regulation (CCIPR) is advocating for the establishment of a federal regulatory body for the horticultural industry and the development of a national database that identifies invasive plants and associated risks in different regions. Cathy Kavassalis, co-founder of CCIPR, emphasized the importance of informing the public about potential harm from invasive plants, similar to existing practices for other products.
The Canadian Food Inspection Agency oversees some invasive plants under the Plant Protection Act, while provinces and territories have their own legislation for invasive species control. The CFIA’s approach focuses on species-specific risks rather than a blanket prohibition on all invasive plants. The agency can restrict the import, sale, possession, and movement of plants identified as regulated pests.
Recent municipal actions include Nanaimo and Surrey’s efforts to restrict the sale of invasive plants listed by the Invasive Species Council of B.C. and London’s recommendation for retailers to provide information on invasive plants to customers. Advocates stress the need for a coordinated approach involving all levels of government to tackle invasive plant management effectively.
Moving forward, advocates are calling for a national database to provide comprehensive information on invasive plants, shared among provinces, territories, retailers, and gardeners. They also recommend removing invasive plants from shelves or clearly labeling them to raise awareness among consumers. Nurseries like Jim Hole support efforts to prevent the spread of invasive plants and emphasize the importance of research, regulation, and public education in combating the issue.
Native plant advocate Lorraine Johnson highlights the industry’s role in biodiversity loss, emphasizing the need for nurseries to prioritize native plant species. Strengthening regulations and public education can help greenhouse owners and farmers in controlling unwanted plants. Regulating garden centers can also help combat “plant blindness” among consumers and encourage a more mindful approach to gardening as part of the broader ecosystem.
