Trinity Western University's code of conduct states students can be expelled if they have same-sex relationships.

Critics say the law school will produce lawyers with an anti-gay bias in a country with anti-discrimination laws and legal gay marriage.

The university has said it welcomes gay and lesbian students.

"We are thrilled with this news," university president Bob Kuhn said in a statement, adding "all students [gay or straight] are welcome to attend Trinity Western University, providing they meet our academic requirements and agree to respect our community values".
