No, we don't and have never needed a majority government. A coalition of LPC, NDP, and BQ would be able to nimbly respond to American threats (because we're all in agreement on that) while preventing a further slide into neoliberalism in the housing market.
If the Liberals gain a majority government and don't hard pivot away from neoliberalism the CPC will be an insurmountable threat next election.
The NDP and BQ are in strong alignment in opposing American expansionism. We can do better than a Liberal majority.
