Child care has been in the news this month, and not always for the best of reasons.

In Ontario, the Ombudsman's office has a new investigation underway into how the province responds to public concerns about unlicensed daycare providers, following the death of a toddler at an unlicensed centre  in Vaughan.

And on Monday police in Kitchener announced the arrest of a former home daycare operator, who was charged in the poisoning of two children.

Here are some numbers on early childhood care and education in Canada.
