Amendments to the Weed Seeds Order (WSO) were published today in the Canada Gazette, Part II to reflect the potential risks posed by weed species in Canada. These changes come into force on November 1, 2016.
The revised WSO includes harmful new species that have been identified and has reclassified existing species based on the most recent information about their distribution in Canada.
The revisions also include the new species of weed seeds to the Class 1 Prohibited Noxious category of the WSO that are already on the list of regulated plant pests in Canada and are thought likely to move through seed.
