Yereniuk has written extensively about the Ukrainian-Canadian community, in such fields as Ukrainians in politics[6][7] and the Ukrainian Orthodox faith.[8][9][10][11][12] He has been vice-chairman of the board of Ukrainian Voice newspaper, and helped oversee the release of the video "Headlines: 90 years of the Ukrainian Voice Weekly" in 2001.[13] In 1990, he co-authored a book entitled Monuments to Faith: Ukrainian Churches in Manitoba, released by the University of Manitoba Press. He later issued a video entitled "The Theotokos in the Ukrainian Religious Tradition", studying icons in Ukrainian religious culture.[14] In 2002, he donated two 16 mm film reels of a 1935 rally in Saskatoon, Saskatchewan of the Canadian Ukrainian Youth Association to the University of Manitoba Archives & Special Collections.[15]
Winnipeg's school board has nine trustees, elected in multi-member wards. Yereniuk first sought election to the board's third ward in 1986, but was narrowly defeated for the final position. He tried again in 1989 and won, and was re-elected in 1992. After the election, he caucused with the New Democratic Party group of trustees.[19]
Yereniuk served as a Regional Director of the Manitoba Association of School Trustees in 1993–1994.[20] In 1994, he voted against a proposal to teach greater tolerance toward homosexuals in Winnipeg schools.[21] Yereniuk indicated that he believed homosexuality should be addressed in schools "with dignity and sensitivity", but argued that it was the responsibility of the provincial government to bring it into the curriculum.[22] He was narrowly defeated in the 1995 municipal election, losing the final position in Ward Three to Luba Fedorkiw. He later began a court challenge against the election of Mike Babinsky, another successful candidate, on the grounds that he had not fulfilled Winnipeg's residency requirements. He dropped the challenge in May 1996, citing financial strain.[23]
Yereniuk returned to the school board in the 1998 election, as the school board shifted to the left.[24] In 1999, he supported a proposal to rehire the city's truant officers.[25] He later opposed the imposition of province-wide language arts exams for grades six and nine,[26][27] and in 2001 suggested introducing Ukrainian-language arts courses for grades nine through twelve at a central location in Winnipeg.[28]
He was re-elected in 2002, and supported a controversial pay raise the following year.[29] In 2003, he called for the Winnipeg School Division to become a partner in the proposed Canadian Museum for Human Rights.[30] He later endorsed a complete ban on smoking in the Winnipeg School Division.[31]
In 2005, Yereniuk was one of three trustees to vote in favour of introducing major changes to the Winnipeg School Board's system of election.[32] He was defeated in the 2006 election, again losing the third position in Ward Three.
