In which provinces must occupiers take reasonable care for the safety of visitors?

The correct choice identifies provinces where occupiers have a legal obligation to ensure the safety of visitors through reasonable care. In Canada, the provinces of Alberta, British Columbia, Ontario, and Nova Scotia have laws that establish this duty, which stems from the Occupiers' Liability Acts. These laws require that those who occupy or control premises take reasonable steps to ensure that visitors, whether invitees, licensees, or even trespassers in some cases, are protected from harm.

By categorizing these provinces as having such legislation, it highlights a shared legal framework that emphasizes the importance of safety standards and liability management. Occupiers must be proactive in identifying hazards and mitigating risks to fulfill this responsibility effectively.

In contrast, the other choices include provinces that either do not have the same explicit duty established by an Occupiers' Liability Act, or they simply do not encompass all the provinces where this duty applies, leading to a different understanding of how occupiers are bound by law to protect visitors.
