An Ontario judge will review the province's police oversight agencies over a fatal police shooting in Toronto.

Ontario's police watchdog found a Toronto officer was justified in killing a man armed with a hammer.

Protesters angry the Special Investigations Unit's report wasn't made public camped out in front of Toronto police headquarters for two weeks.

They also marched on the legislature to call for an overhaul of the agency.

Attorney General Madeleine Meilleur says Appeal Court Justice Michael Tulloch will lead an independent review of Ontario's three police-oversight agencies: the S-I-U, the Office of the Independent Police Review Director and the Ontario Civilian Police Commission.

She says Tulloch will examine how S-I-U reports could be made public in the future, as well as whether past reports could be published.
