While members of various faiths were invited, according to Kaufman of the Edmonton Sun, the Sunni Muslim group Islamic Supreme Council of Canada, led by Syed Soharwardy, was not invited, due to its belief that Ahmadiyya Muslims are not "real" Muslims, and did not consider Baitun Nur a "mosque."
Praise for the Ahmadiyya Muslim Community came from attendees, including Harper, who said "Calgarians, Albertans and Canadians will see the moderate, benevolent face of Islam in this mosque and the people who worship here."  According to Embassy magazine, regarding Harper's remarks, a governing party insider said "It's an important signal the prime minister is sending, not just to militant Islamists abroad, but to their sympathizers here at home, that he's perfectly prepared to ignore them and side with persecuted minorities within the faith."
