As far as I can understand, the recommendations regarding helmets are unsubstantiated. Here are the relevant bits I could find.
The logic seems to be: more deaths without helmet --> helmets save lives
Interesting article in the Globe and Mail this morning. It pegs Ontarios helmet usage rate at 31%, which places the stat of 26% of cyclists wearing helmets dying in a different perspective.
I think this (missing) information discredits the Coroners recommendation
