Belgrave's 2008 collapse left more than 1200 investors $22 million out of pocket.
Hamilton was found guilty of 14 charges of theft by a person in a special relationship in 2014, and sentenced to four years and nine months prison.
He was released on parole in 2016, with three years left on his sentence.
The parole board said at the time they did not see him as an undue risk to public safety.
"He is a mature, compliant and polite prisoner who has a minimum security risk. He was struck off as a lawyer as the result of his offending. He says that he will not become involved again with any legal activity or financial involvement," the board said.
