Who Is Liable for a Slip on a Commercial Lot in Alberta?

By Brenden Lidder, Owner, PWW Services Inc.

The short answer

Usually the occupier. Alberta's Occupiers' Liability Act puts a duty of care on the person who has responsibility for and control over the premises, which may be the owner or a tenant depending on who controls the site. Hiring a snow contractor does not automatically shift that duty; the Act expects reasonable care in choosing and supervising the contractor.

Who is the occupier

Section 1(c) of the Occupiers' Liability Act includes a person who has responsibility for and control over the condition of premises, the activities conducted on them and the persons allowed to enter. On a leased lot that can be the landlord, the tenant or both, depending on who controls the site. Check the lease.

The duty of care

Section 5 requires the occupier to take the care that is reasonable in all the circumstances to see that visitors will be reasonably safe in using the premises for the purposes they were invited or permitted to be there. In winter that includes snow and ice on lots, entrances and walkways.

Does a snow contractor take on the liability?

Section 11 says an occupier is not liable for damage caused by an independent contractor's negligence if the occupier took reasonable care in selecting and supervising the contractor and it was reasonable to hand the work over. A contract does not remove the occupier's own duty.

The City sidewalk is a separate duty

In Grande Prairie, Bylaw C-1166 s. 38 requires the owner or occupant to clear the adjacent sidewalk within 24 hours of the most recent snow or ice.
