He was a founder of Winnipeg's Block Parent Program in this period and served on several community boards, as well as being on the executive of the Ukrainian Legion Branch #141.
[3] In the 1980s, Chornopyski was an opponent of NDP Premier Howard Pawley's plans to legally entrench French-language services in the province.

In the provincial election of 1986, Chornopyski contested the riding of Burrows as an independent candidate, and lost to incumbent New Democrat Conrad Santos by 2110 votes.
