Canadian cities are taking steps to prevent the sale of invasive plants in local garden centers, while advocates are urging the Canadian government to establish a national framework for regulating the horticultural industry. Invasive plants pose a threat to biodiversity nationwide, prompting municipalities to address gaps in the current regulatory system, which varies by region. Canada has set a goal to reduce the introduction and establishment of known invasive species by 50% by 2030.
The Canadian Coalition for Invasive Plant Regulation (CCIPR) is calling for the creation of a regulatory body by the federal government to oversee the horticultural sector and develop a national database identifying invasive plants and associated risks in different areas. Cathy Kavassalis, co-founder of CCIPR, emphasized the importance of informing the public about potential harm posed by invasive plants, advocating for similar consumer protection measures applied to other products.
While the Canadian Food Inspection Agency (CFIA) regulates some invasive plants under the Plant Protection Act, individual provinces and territories have their own legislation governing invasive species and weed control. The CFIA highlighted that their approach focuses on species-specific and risk-based restrictions rather than a blanket prohibition. They collaborate with provinces, municipalities, industry stakeholders, and invasive plant organizations to manage invasive species effectively.
Recent actions in various Canadian cities reflect the growing concern over invasive plants. Nanaimo and Surrey have moved to restrict sales of plants listed by the Invasive Species Council of B.C., while London’s environmental committee recommended retailers to provide information about invasive plants to customers at the point of sale. However, advocates like Kavassalis stress the need for a comprehensive national strategy to address the issue instead of fragmented local efforts.
Experts, including horticulture specialist Jim Hole, support efforts to curb the spread of invasive plants, with emphasis on education and regulation. They emphasize the role of nurseries in preventing the introduction of invasive species through plant sales. Lorraine Johnson, a native plant advocate, highlighted the industry’s influence in promoting non-native plants and the negative impact on biodiversity, emphasizing the importance of native plant gardens for supporting pollinators.
Advocates are calling for a centralized national database to inform stakeholders about invasive plant risks and promote responsible gardening practices. By raising awareness and implementing stricter regulations, stakeholders aim to mitigate the environmental and economic harm caused by invasive plants, emphasizing the collective responsibility of governments, industry, and consumers in combating this pervasive issue.
