It stands to reason. O'Leary is pretty liberal (for lack of a better term) especially on social issues while Leitch is fairly right wing (especially on social issues). If I were Canadian, I'd still support Trudeau's Liberals but I wouldn't feel like the earth is falling apart if O'Leary Tories won. Can't say I'd feel the same way with Leitch.
Of course, polls were wrong here stateside...
She's fairly right wing on immigration. Not so much on social issues. She marches every year in Toronto Pride, supports same sex marriage, supports government funding for gender re-assignment surgery, has stated she does not want to re-open the abortion debate, supported adding "gender identity" and "gender expression" to the Human Rights Act and Criminal Code.
I don't agree with her stance on the "Values test", but she is far from being right wing on social issues.
