Myron Maksymiw founded Musicus Bortnianskii (Toronto) in 1981 to foster the works of Ukrainian baroque and classical composers. In addition to working with choirs in Canada and Ukraine, he has researched, transcribed, edited, and published a staggering amount of Ukrainian non-secular (religious) choral music over the past 40 years. A champion of Dmytro Bortniansky, Mr. Maksymiw has premiered most of the composer's music. In 2015, he initiated and organized an annual Festival of Ukrainian Choirs, bringing together choirs from many Ukrainian churches and cathedrals in the GTA.
