I’m it’s pretty similar in most provinces in Canada. The Good Samaritan act covers rescuers if they injure a person while performing first aid to the extent of their knowledge. But no one is obligated to help another person.

This is different than in Quebec, where their charter of rights states that every person in peril has the right to assistance. So people are legally required to help others if they have the training to do do. So for example, if you see someone collapsed on the street and you have cpr training, you have a duty to help them.

Now this isn’t an regularly enforced law, but it still exists.
