A former taxpayer ombudsman for the federal government has been selected by an all-party panel as Ontario's new ombudsman.

Paul Dube's five-year term starts April 1.

Ontario's previous ombudsman was the outspoken Andre Marin, a vocal advocate with a flair for the dramatic.

He waged a social media campaign last year in a last-ditch effort to get reappointed for a third term, but the Liberal cabinet bypassed the opposition parties and appointed Barbara Finlay as a temporary ombudsman until the search for a permanent one could be completed.

Marin is famous for the blunt language in his special reports on everything from the mass violation of civil rights during the G20 in Toronto to huge billing errors by Hydro One.
