Jagmeet Singh is calling on Ottawa to provide the provinces with billions in funding for child care — a demand that could help determine whether the minority Liberal government survives.With the support of the Liberals, the NDP passed a motion this week calling on the federal government to immediately transfer $2 billion to the provinces for child care.Singh is now upping the ante, calling for another $10 billion over the next four years.Singh says $2 billion is needed this year just to ensure there are enough child-care spaces available to allow parents — particularly mothers — to go back to work now that restrictions to curb the spread of the COVID-19 pandemic are being relaxed.
