Mark Gregory Brazau was 32 when he was reported missing to Toronto police on May 23, 2007. He was last seen at his workplace in Toronto. At the time he disappeared he was described as a Caucasian male, 6 feet tall, 201 pounds, with brown receding hair, a beard and mustache, a mole on his left cheek, a scar on his right knee and a tattoo on his left arm.

Officers found his residence had been empty for about three months before the missing-person report, and there was no financial activity in his accounts after he was last seen. Those facts suggest a prolonged absence rather than an immediately recent disappearance; beyond that, there has been no confirmed trace of his whereabouts.

The Toronto Police Service maintains a file on the case. Occasional online discussions have tried to link him to unidentified remains recovered elsewhere, including an unidentified man found in the Richelieu River in 2010, but no connection has been confirmed.

If anyone knew Mark, saw him in Toronto in spring 2007, or has information that could clarify where he went, please come forward.
