Lisitsa has received criticism for her vocal opposition to the Ukrainian government and support of pro-Russian separatists since the 2014 pro-Russian unrest in Ukraine and the ensuing armed conflict. In April 2015, the Toronto Symphony Orchestra cancelled concerts with Lisitsa, citing her "provocative" online remarks on her Twitter account; the orchestra initially did not specify which tweets or other commentary it believed crossed a line. Later, on 8 April 2015, the CEO of Toronto Symphony, Jeff Melanson provided a PDF document of seven pages listing the most "offensive" tweets. Melanson alleged that the document would "help people understand why we made this decision, and understand as well how this is not a free speech issue, but rather an issue of someone practicing very intolerant and offensive expression through Twitter."
