Canadian municipalities are taking action to prevent the sale of invasive plants in local garden centers while urging the Canadian government to establish a national strategy for regulating the horticultural trade. In response to invasive plants posing a threat to biodiversity nationwide, local governments are stepping in to address gaps in the current regulatory framework, which 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 create a regulatory body for the horticultural industry and develop a national database that identifies invasive plants and their associated risks in different areas. CCIPR co-founder Cathy Kavassalis emphasized the importance of informing the public about potential harm from invasive plants, drawing parallels to existing product safety regulations.
While the Canadian Food Inspection Agency (CFIA) oversees certain invasive plants under the Plant Protection Act, individual provinces and territories have their own legislation for managing invasive species. The CFIA stated that their approach focuses on species-specific risks rather than a blanket prohibition on all invasive plants, acknowledging that collaborative efforts with other stakeholders are crucial for effective invasive plant management.
Recent initiatives in Canadian cities reflect growing concerns about invasive plants. Nanaimo and Surrey have taken steps to restrict the sale of invasive plants, while London’s environmental committee recommended mandatory information provision to customers by retailers selling invasive species. Advocates, such as Kavassalis, stress the need for coordinated efforts at all levels of government to address the spread of invasive plants effectively.
To achieve the federal government’s 2030 target, Kavassalis emphasized the importance of regulating the horticultural trade. Studies have highlighted the role of ornamental non-native plants in introducing invasive species, underscoring the need for a national database to facilitate informed decision-making. Suggestions include removing invasive plants from sale or providing clear labeling to raise awareness among consumers.
Experts like Jim Hole support efforts to prevent the spread of invasive plants, noting that most garden centers would cooperate with regulations to protect ecosystems. Native plant advocate Lorraine Johnson highlighted the influence of nurseries on consumer choices and biodiversity loss, advocating for a shift towards native plants to support local ecosystems and pollinators.
Regulating garden centers can not only prevent the inadvertent spread of invasive species but also raise public awareness about the importance of choosing plants that support local ecosystems. This approach aims to combat “plant blindness” among gardeners, encouraging a more mindful approach to landscaping that considers the broader environmental impact.
