Opposition leaders are reacting to reports staff for Public Safety Minister Marco Mendicino did not inform him of the transfer of convicted rapist and killer Paul Bernardo.

Conservative Leader Pierre Poilievre says he believes the Minister knew all along.

"He's lied about his knowledge and role in moving Paul Bernardo from a maximum security penitentiary to a medium security penitentiary. These are too many lies, its one lie too many, it is time for Marco Mendicino to resign."

Meanwhile Bloc Quebecois leader Yves-Francois Blanchet says this is more of a question for the Prime Minister.

"We ask the Prime Minister the question in the debate before an election, but I'm not to ask for every Minister that says 'he or she is ignorant', which seems to be the case of quite many of them that they should resign."

Blanchet believes replacing Mendicino would just result in more of the same issues.

Bernardo was sentenced to life in prison with no chance of parole for 25 years in 1995 for the killings of teenagers Kristen French and Leslie Mahaffy, he was also convicted of manslaughter for his role in the death of Tammy Homolka.
