One of Canada's most prolific rapists has been granted day parole in B.C.'s Lower Mainland, CTV News has learned.

Larry Takahashi's crimes were committed against at least 30 women in Edmonton between 1979 and 1983. He was dubbed the Balaclava Rapist for his pattern of sneaking into homes to assault women while wearing a ski mask as a disguise.

He was convicted of 14 charges and handed three life sentences, but was released in Victoria in 2013 on an unescorted temporary absence. While he stayed in a halfway house, local police issued a warning that he poses a significant risk to adult and teenage girls.

Takahashi was back behind bars just days after his release into the halfway housebecause of public outcry. He was also granted day parole in 2003, but it was revoked two years later because he wasn't being truthful with his parole officer.

Nearly three years later, officials confirmed Tuesday that Takahashi has been granted day parole in the Lower Mainland, but did not provide a specific location. He initially asked for full parole, but was denied.

Takahashi will be subject to a strict curfew of 9 p.m., and will have to spend every night at a halfway house. While on day parole, he cannot use alcohol or drugs, and must undergo treatment for sexual deviancies.

He is not permitted to watch pornography, can have no contact with his victims or their families, and cannot be near college or university campuses. He is also not allowed to use a computer or the internet, and must report all relationships to his parole officer.

His day parole will last six months, then he will be reassessed.
