The Alberta Act requires the control of noxious weeds and the destruction of restricted weeds. Action requirements under the Acts of each province are outlined below. The British Columbia Act specifies that regulation for control under the Noxious Weed Act cannot be made until they are approved by the Environment and Land Use Committee established under the Environment and Land Use Act . Control practices for the single species to which the Act applies are outlined in the regulations. It is the Minister of the Environment who has the power to implement a control program.
Most Acts require all occupiers of land to control or destroy noxious weeds thereon.
Where there is no occupant or where the occupant resides outside the jurisdiction of the by-law, the landowner is responsible. In Ontario and Prince Edward Island, it is the landowner who is required to control weeds. In Quebec, the responsibility for control resides with landowners, land occupiers and persons operating land. Under the Manitoba Act, responsibilities for weed control are also laid out for earthwork and land between the low water mark and the limit of owned property. Only three Acts outline wide-ranging responsibilities for weed control on Crown land.
