Cathedral of the Nativity of the Mother of God, Slovak Byzantine Catholic cathedral on Shaw Street, Toronto, Canada

The Cathedral of the Nativity of the Mother of God occupies a former B'Nai Israel synagogue on Shaw Street in Toronto, bought by the congregation in the early 1950s and converted into a church. It serves the Exarchate of Saints Cyril and Methodius of Toronto. As of 2024 the interior still lacked an iconostasis, a screen of icons the parish had never installed since the conversion; fundraising for a renovation, including one, began that year.

The building began as a synagogue but was later converted for use as a cathedral to serve the local community for decades. Over time it underwent changes in administrative oversight due to ecclesiastical decisions.

The parish was founded in October 1951 for Toronto Slovaks of the Eastern Rite, with L. Minya as first pastor. Its Byzantine Catholic worship follows the Ruthenian Greek Catholic Church, under which the exarchate was placed in 2022. A long-planned iconostasis, which the building never had as a converted synagogue, was a goal of the 2024 renovation fundraising.

The cathedral stands on Shaw Street, north of Queen Street West in Toronto. The 2024 fundraising for renovation, including a first iconostasis, means interior work may be under way, so check access before visiting. It serves the Slovak Byzantine Catholic exarchate under the Ruthenian Greek Catholic Church.

The congregation bought the B'Nai Israel Synagogue on Shaw Street in 1952, during Michael Rusnak's time as pastor, and converted it into a church. As a result, the cathedral never had an iconostasis; fundraising for one began in 2024.
