A former top military chaplain is facing sex charges for incidents that allegedly happened in 1972 at CFB Borden in Ontario, military investigators said Tuesday.

Roger Bazin, a retired chaplain-general, was arrested in Barrie, Ont., and has been charged with one count of buggery, one count of an act of gross indecency, and one count of indecent assault on a male, according to the Canadian Forces National Investigation Service.

The alleged crimes fall under the 1972 Criminal Code of Canada, the statute in effect at the time of the offences, hence the now-discarded "buggery" charge.

Bazin held the rank of captain at the time of the alleged incidents. He later served as head of the military chaplaincy from 1992 to 1995.

The alleged victim made the allegations against Bazin in June 2009, which led to a military police investigation.

"The military police consider this to be a serious matter and will thoroughly investigate any such allegations related to CF [Canadian Forces] members, DND employees or defence establishments," Col. Tim Grubb, Canadian Forces Provost Marshal, said in a statement.

"These types of alleged acts, if proven, are illegal and represent unacceptable conduct."

Bazin has been served with a notice to appear in Barrie Provincial Court on April 28.

Brig.-Gen. David Kettle, the current chaplain-general, said he was shocked by the allegations.

"I will not comment on the charges as they are being dealt with by the criminal justice system, but I am certain that I speak for all chaplains when I say that my heart goes out to the victims of such crimes, and their families," he said in a statement.
