Bruxy Cavey, the leader of Toronto's Meeting House Church, has stepped down following an investigation into his behaviour.
It comes after a sexual misconduct accusation was made in December following which he was suspended.
The Meeting House Overseers Board say they've received the findings of the report and have asked Cavey to resign.
The report found he had maintained a sexual relationship which constituted an abuse of power and amounted to sexual harassment.
In a statement, the board said: "Due to the seriousness of the investigator's findings, our Board unanimously decided to ask Bruxy to resign from his role at The Meeting House effective immediately. Bruxy then submitted his resignation on March 3rd, which the Overseers accepted.
"The Meeting House stands against sexual misconduct, sexual harassment, and abuse of power and authority. We are praying through this situation."
On the same day the statement was released, Cavey made his own statement on his website.
In a blog post titled 'My confession', he said: "At the core of these allegations there is truth.
"Some years ago, I had an extramarital affair.
"I am ashamed even to write these words, and I am so sorry that you have to read them. This adulterous relationship is my greatest failure, my darkest sin, and I take full responsibility for my actions.
"I have broken bonds of trust with my wife, family, and church family, including the woman I became involved with. I have brought untold pain, heartache, and confusion into the lives of those I love and who love me.
"I am deeply sorry."
The Meeting House, which has 19 campuses across Toronto and over a hundred house churches, is yet to indicate how it will move forward following the resignation, however Danielle Strickland, the renowned preacher who was a teaching pastor at the church has also announced her resignation in solidarity with the victim.
Writing on Twitter, she said she will be releasing a statement from the victim imminently.
