Check: this sitting fuses the policy-statement definition, the issues it should cover, AND who holds responsibility under it into a single 7-mark sub-part (ii); sub-part (iii) covers safety standards, and sub-part (i) covers the OHS program itself and its basic elements.

(i) What an Occupational Health and Safety Program Is, and Its Basic Elements

An Occupational Health and Safety (OHS) program is the organized, documented set of policies, procedures, and activities an employer establishes to systematically identify, assess, and control workplace hazards; to comply with the applicable Occupational Health and Safety Act and its regulations; and to prevent injury, illness, and property loss on an ongoing basis. Where the policy statement (part ii) is the one-page commitment at the top of the internal responsibility system, the OHS program is the operational structure that carries that commitment out day to day across every workspace, regardless of whether the workplace is a heavy-manufacturing plant, an office, or a field site.

Basic program elements that should be present, regardless of the specific workspace:

These elements are the same in kind across every workspace — what changes from an office to a heavy-industrial plant is the specific hazards each element must address (ergonomic and fire-egress hazards in an office vs. machine-guarding, chemical, and confined-space hazards on a plant floor), not whether the element itself is present.

(ii) Definition of a Policy Statement, the Issues It Should Cover, and Who Holds Responsibility Under It

A policy statement, as contemplated by Ontario's Occupational Health and Safety Act (OHSA) and its provincial/territorial equivalents across Canada, is a short, dated, and signed written statement issued by the employer — normally over the signature of the most senior officer on site — that publicly commits the organization to protecting the health and safety of every worker and establishes, at a general level, how that commitment will be carried out. It sits at the top of the internal responsibility system (IRS): it does not itself contain detailed procedures, but authorizes and mandates the OHS program elements of part (i) that implement it, and it is normally required to be posted where workers can see it and reviewed at least annually.

Issues the policy statement should cover:

Responsibility under the policy maps directly onto the internal responsibility system (IRS) that Canadian OHS legislation is built on: every party in the workplace carries a share of responsibility proportional to the authority it holds, and no single party (least of all the individual worker) carries the whole burden.

The three worker rights that Canadian OHS law builds around — the right to know, the right to participate, and the right to refuse unsafe work — are the practical mechanism through which a worker's responsibilities under the policy are exercised without placing on that worker a duty they have no authority to discharge alone.

(iii) Need, Objectives, and the Reporting/Investigation/Analysis Cycle of Safety Standards

Safety standards (e.g., CSA Z1002, Z432, and the many hazard- and equipment-specific standards referenced by OHSA regulations) exist because a general statutory duty ("take every reasonable precaution") is not, by itself, specific enough for a designer, purchaser, or inspector to verify compliance against. Standards translate the general duty into measurable, auditable, and consistently applied requirements — a guard height, a permissible noise exposure, a minimum air-change rate — so that "reasonable" has a concrete, defensible meaning across the industry rather than being re-argued after every incident.

Their objectives, and how the reporting → investigation → analysis → prevention cycle they define operates:

Without this cycle, safety performance is driven only by hindsight after a serious injury; with it, standards give the organization both a target to design toward before an incident occurs and a structured mechanism to learn from the incidents that do occur.
