When does absolute privilege protect a statement from a defamation claim in Ontario?

Absolute privilege provides complete protection from a defamation claim for statements made in specific, defined settings - most notably statements made during court or tribunal proceedings, and statements made in Parliamentary or legislative proceedings - regardless of whether the statement was actually false or made with malicious intent. Unlike qualified privilege, absolute privilege cannot be defeated by proving the speaker acted maliciously or dishonestly; it exists because certain proceedings depend entirely on participants being able to speak freely without fear of a later lawsuit over what they said.

This is considered more important to the functioning of the justice and legislative systems than protecting any individual's reputation in that specific, narrow context. The protection is deliberately narrow and tied to the specific proceeding itself - it generally does not extend to repeating the same statement later outside that protected setting, such as discussing courtroom testimony afterward in a way that repeats the defamatory content in a new, unprotected context outside the original proceeding.
