Canadian cities are making efforts 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 regulatory gaps that exist across jurisdictions. 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 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 regions.
CCIPR co-founder Cathy Kavassalis emphasized the importance of informing the public about potential harm posed by invasive plants, suggesting that similar to other products, plants should also come with relevant information. The Canadian Food Inspection Agency regulates some invasive plants under the Plant Protection Act, while provinces and territories have their own legislation for invasive species and weed control.
While the CFIA adopts a species- and risk-based approach rather than a blanket prohibition on all invasive plants, it can restrict the import, sale, possession, and movement of plants classified as regulated pests. The agency highlighted that managing invasive plants is a joint effort involving federal, provincial, municipal, industry, and organizational collaboration.
Various municipalities such as Nanaimo, Surrey, and London have taken steps to restrict the sale of invasive plants through local regulations. Advocates stress the need for a cohesive national strategy to effectively tackle the issue, emphasizing the role of all levels of government in finding solutions.
Experts like Jim Hole, a horticulture and agriculture specialist, believe that most garden centers would support measures to prevent the spread of invasive plants. They underscore the importance of research, regulation, and public education in controlling unwanted plant species.
Native plant advocate Lorraine Johnson points out the influence of nurseries in shaping consumer choices and biodiversity outcomes. She emphasizes the significance of distinguishing between native and non-native plants to support ecosystems and pollinators effectively.
In conclusion, the call for coordinated efforts at all levels of government, stringent regulations, and public awareness campaigns underscores the urgency of addressing the sale and spread of invasive plants in Canada’s horticultural industry.
