In Vancouver (excluded suburbs), there is currently the first-ever large scale cycling program for children to develop safe cycling skills.

My understanding is that the program will target approx. 3,000 school children across several schools over a period of less than 2 months. The program is currently led by a cyclist, a retired school principal. His lobbying efforts have been supported by a few cyclists, who themselves are school teachers.

The program coordinator(s) approach the target schools and work via key teachers in each school.

It's a great foundation to start.

I pass several schools on my regular cycling rides in early morning these past few weeks. Only 1 school, I noticed total of less than 5 different children on a bike..usually accompanied by an adult.
