Alberta Weed Control Act Compliance
Under the Alberta Weed Control Act, landowners and occupants, including oil and gas lease holders, are legally required to control noxious weeds on their land. Municipal weed inspectors can issue notices requiring treatment within specified timelines. Failure to comply results in the municipality performing the work at the landowner's expense.
