Canadian municipalities are taking action to prevent the sale of invasive plants in local garden centers, calling for a unified national approach to regulate the horticultural trade. As invasive species pose a threat to biodiversity nationwide, cities are stepping in to address gaps in the varying regulatory systems. Canada has committed to reducing 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 industry and develop a national database that identifies invasive plants and their associated risks in different regions. CCIPR co-founder Cathy Kavassalis emphasized the importance of informing the public about potential harm from invasive plants, similar to how warnings are provided for other products.
While the Canadian Food Inspection Agency oversees some invasive plants, individual provinces and territories have their own legislation to control invasive species. Recent initiatives include Nanaimo and Surrey passing motions to restrict the sale of invasive plants listed by the Invasive Species Council of B.C., and London’s environmental committee recommending retailers to provide information on invasive plants at the point of sale.
Advocates like Kavassalis stress the need for a comprehensive national strategy to tackle invasive plants, highlighting the role of the horticultural trade in introducing harmful species. Efforts to create a national database and remove or label invasive plants in stores could aid provinces, territories, retailers, and gardeners in making informed decisions.
Experts like horticulturist Jim Hole support measures to curb the spread of invasive plants, noting that most garden centers would cooperate with such regulations. Enhancing research, regulation, and public education can benefit greenhouse owners and farmers by reducing the impact of unwanted species on the environment.
Native plant advocate Lorraine Johnson pointed out that many consumers are unaware of the invasiveness of certain plants, emphasizing the industry’s responsibility in promoting biodiversity. By regulating garden centers, authorities can help raise awareness among gardeners and foster a deeper appreciation for the interconnectedness of plant life within the broader ecosystem.
