David Burke is a Mission Canada campus worker to Ryerson University, situated in the core of downtown Toronto. Ryerson is home to over 43,000 students, the majority of whom do not know Christ as their Saviour. David, along with his wife, Krysten, launched a ministry on campus called "LifeLine" to help fill this spiritual need. LifeLine exists to be a vibrant faith community that is actively introducing people to Jesus Christ, and discipling and mentoring those who do know Him.
