The opening as it read in 2015

Jami Mosque ( مسجد جامع ) is the oldest Canadian Islamic centre in the city and dubbed "the mother of all the mosques in Toronto".1 Built in 1910 as a Presbyterian church, the building was purchased in 1969 by Toronto's small, predominantly Balkan , Muslim community and converted into the city's first worship centre.2 In November 1977, Ahmed Khadr and Maha el-Samnah were married at the mosque.3 While Jami originally held a large number of Tablighi Jamaat followers, the numbers declined after a large influx of Gujarati Muslims immigration led to the leasing of a hall in eastern Toronto; and the eventual 1981 purchase of a building converted to Madina Mosque , which became the spiritual hub of Tablighi Jamaat. Jami then drifted towards finding leadership in the Muslim Students Association .4
