Regulation - LGIC

Updating the Schedule of Noxious Weeds in R.S.O. 1990, Regulation 1096 General made under the Weed Control Act - R.R.O. 1990, c. W.5 (removal of goat's-beard spp., nodding thistle spp., Scotch thistle and wild carrot)

Regulation Number(s):
Regulation 1096
Instrument Type:
Regulation - LGIC
Bill or Act:
Weed Control Act, R.S.O. 1990, c. W.5
Summary of Decision:
The regulation has been approved. The regulation includes some changes from the original proposals. These modifications respond in part to comments received as a result of the posting.

For more information on changes that resulted from the consultation, please read the related postings on the Environmental Registry (under EBR Registry Numbers 012-1205 and 012-2634). These are accessible via the links on this page.

Nine weeds were added to the Schedule of Noxious Weeds (smooth bedstraw, wild chervil, common crupina, jointed goatgrass, kudzu, wild parsnip, serrated tussock, tansy ragwort and woolly cupgrass). These weeds are considered to be emerging threats to the agriculture industry in Ontario. Some of the species added have previously caused large losses in crop revenues in other jurisdictions (e.g., kudzu) and are of growing concern to Ontario farmers. These weeds will have to be destroyed in areas where they will negatively affect agricultural land, crops or livestock.

In addition, nine plant species were removed from the Schedule (wild carrot, nodding thistle species, goat's-beard species, Scotch thistle, Johnson grass, black-seeded proso millet, yellow rocket, Russian thistle and tuberous vetchling). These plant species are no longer considered significant threats and can be managed through modern management practices. Additionally, several of the removed species are food sources for pollinators.

The regulation will come into force on January 1, 2015.

- Scotch thistle (Onopordum acanthium L.)
