Several Canadian cities are considering local bylaws to limit the sale of invasive plants at nurseries and garden centres. This move comes as concerns rise over the impact these plants have on Canada’s biodiversity. Advocates from the Canadian Coalition for Invasive Plant Regulation are pushing for a national approach, suggesting the creation of a federal horticulture body. They also propose establishing a comprehensive invasive plant database to track and manage the spread of harmful species. Supporters believe these measures are crucial to address what they describe as a growing biodiversity crisis. A federal framework, they argue, would provide consistency and greater effectiveness compared to a patchwork of municipal regulations. The current situation relies heavily on local initiatives, leading to varying levels of control across the country.
