Yes, there have been a number of studies on the subject. The witnesses you will be hearing later will tell you more about that, I believe. Studies have shown that putting programs like this in place in the schools would improve children's learning and well-being as well as their relationships with their classmates.
Those benefits have a knock-on effect in their adult lives. These kids do better in life because they have had a good start in school. Studies have proven this for several years now. It is time for Canada to set up a program like this in all schools in the country.
