In 1990, he was called as rector of the Anglican Church of the Good Shepherd, a predominantly ethnic Chinese congregation in the Diocese of New Westminster in Vancouver.

[2] As the Anglican realignment proceeded in Canada, Church of the Good Shepherd voted unanimously[3] to disaffiliate from New Westminster in February 2008.

[3] The church was involved in litigation over the ownership of its property; the Supreme Court of British Columbia (a trial court jurisdiction) in 2009 affirmed that the property belonged to the diocese, but the judge awarded a $2.2 million bequest to the local congregation, finding that "Dr. [Daphne Wai-Chun] Chun intended the proceeds [of the bequest] to be applied to the building needs of the parish that served the Chinese community.

In the circumstances, I conclude that a scheme whereby the funds are held on trust for the building needs of the ANiC congregation will best fulfil Dr. Chun’s charitable intent.

[5] On November 13, 2009, Leung was consecrated a bishop for ANiC in St. Catharines, Ontario, alongside Charlie Masters and Trevor Walters.
