[5] Rubess was a member a theatre collective called The Midnight Hags, founded by Mary Ann Lambooy.
The collective created a piece called Burning Times which premiered in August 1983 at The Theatre Centre.
Burning Times used quotations from the Malleus Malificarum and told the story of female travellers who encountered the witch hunts.
After the initial production, Lambooy distanced herself from the collective and eventually wrote a letter to Nightwood Theatre to attempt to bar the group from re-staged Burning Times by invoking her copyright ownership.
By December 1983, Lambooy stated that she would not give up copyright to Burning Times in addition to refusing to acknowledge Rubess as its principal author.
The Anna Project consisted of Rubess, Suzanne Odette Khuri, Ann-Marie MacDonald, Patricia Nichols, Tori Smith, Barb Taylor, and Maureen White, though the play is usually credited only to Khuri, Macdonald, Rubess, and White.
[11] Rubess' play Froth, a theatrical exploration of shopping and materialism, premiered as a work-in-progress in 1994 as part of The Gathering, a women's theatre festival in Toronto.
The production was staged at Kensington Market and featured Alisa Palmer, Susan McKenzie, and Rubess herself as actors.
