The main purpose of the Weed Control
Act R.S.O. 1990 is to reduce the impact of noxious weeds on the
industries of agriculture and horticulture. Primarily this act applies
to agricultural and horticultural lands that generate income or other
benefits to agriculture; this excludes lawns, gardens and private areas
for personal enjoyment and leisure.
Under the Weed Control Act, R.S.O.
1990, Chapter W.5 Sections 3, 13, 16 and 23, residents are requested to
destroy all noxious weeds on their property.
In Urban Areas, Sections 3, 13, 16 and
18 do not apply to noxious weeds or weed seeds that are far enough away
from any land used for agricultural or horticultural purposes, as they
do not interfere with that use.
