Acts are often deliberately vague, or open to interpretation. More specific guidelines are often created using Regulations under an Act. This gives regulators some leeway - it is easier to create or amend regulations through Cabinet than to create or amend an act using the full legislative process. An act does not necessarily have regulations. An act may be considered specific enough in and of itself.
Regulations are a form of law, often referred to as delegated or subordinate legislation.
They have the same binding legal effect as Acts and usually state rules that apply generally, rather than to specific persons or things. However, regulations are not made by Parliament. Rather, they are made by persons or bodies to whom Parliament has delegated the authority to make them, such as the Governor in Council, a minister or an administrative agency. Authority to make regulations must be expressly delegated by an Act. Acts that authorize the making of regulations are called enabling Acts.
