Last Month, Rueben Removed a Tall Tree in His Backyard

Last month, Rueben removed a tall tree in his backyard. He left the large hole because he intended to plant a new tree when the rains began. Sunday, he invited his neighbour, Joe, to come over to watch the Olympics. When Joe came, he cut through the backyard and fell into the hole and broke his arm. Which of the following is true with regard to the liability of an occupier of land?

A) The standard of care is set by a federal statute and is therefore the same for all the provinces.
B) An occupier owes a duty only to "licencees."
C) There is no duty of care owed to persons who come onto another's property whether invited or not; persons must take responsibility to look after themselves.
D) The standard of care imposed on the occupier is set by provincial statute.
E) A tenant cannot be liable; only the owner can be sued.
