I was placed in an 'enriched' class outside my normal catchment area starting in Grade 4 (age 9).  Had to take the bus on my own every day.   Not terribly far but still.  Zero problems.
At about that age, on weekends and when any chores were done, my best friend and I would cycle all over Wpg. We each had a dollar or two in case we got thirsty or needed to make s phone call.  This happened a couple of times but was basically a non-issue.
When 16, I went to Expo 67 on my own. Stayed at a hostel. Snuck a few beers.  Nothing bad happened.
Helicopters my parents were not, and I am much the better for it.  This situation in BC is ludicrous, bureaucratic overkill.  There are not monsters behind every bush or fence.
