How many children don’t eat lunch on school days in Canada? A new study documents the gaps of current school food programs

A recent study published by the University of Ottawa found that over 1 in 20 Canadian children do not eat lunch on school days, with older kids and those from food-insecure households being the most affected. The study also reveals that children living in food-insecure households are twice as likely to miss lunch compared to their peers.
