The two measures Mulcair praised were in the NDP platform. Then he is SHOCKED to find there was no reference to childcare in the WHOLE speech. Why would there be? It wasn't part of Trudeau's platform and he didn't mention it in any speeches.
Actually, child care is a part of the Liberal platform under "social infrastructure", and is covered in the Liberal policy resolutions. See https://www.liberal.ca/policy-resolutions/3-national-strategy-universal-...
So it makes sense for Mulcair to call them out on this.
ETA: From their platform:
With historic new investments in social infrastructure, we will achieve both.We will improve quality of life for millions of Canadians by prioritizing investment in affordable housing, seniors’ facilities, early learning and child care, and cultural and recreational infrastructure.
