The Ukrainian Catholic Church of the Great Martyr Saint George the Victorious in Edmonton has a thorough webpage explaining its iconography.
The link to this website was sent to me by a friend of the iconographer, Heiko Schlieper. Memory eternal.
This parish was one of several organized in the 1950s and 1960s championing Ukrainian Catholic traditionalism, Byzantine iconography, delatinized liturgy, and the Julian Calendar. Another such parish is the extraordinary Ss. Volodymyr and Olha in Chicago, about 2 miles directly west of my apartment, which I visit on occasion.
