An electoral result such as this one would be a gift to the Bloc Quebecois.
Liberal minority would require the support from both the NDP and the Bloc. Giving the Bloc a lot of power since it is not worried about opinions in the rest of Canada, unlike the NDP is.
The only possible ally to a CPC minority would also be the Bloc. I doubt the NDP would support the CPC and the Libs could potentially support some policies but working as a coalition would be suicidal for a party wanting to form government.
As for the Bloc and a CPC minority, the BQ can always say : "we are trying to make government work, people don't want another election" while it corners the CPC on giving Quebec even more autonomy.
Quebec's stated demands to Ottawa
What the Bloc could possibly want also
A CPC minority supported by the Bloc would be a bonanza for Quebec.
Although, the CPC could also pass a deal with the Libs to block the demands from Quebec.
