Is Vancouver safe enough to let your 5-6 year old to explore the area by themselves?

I know that in some other countries, it is the norm since the area is very walkable, and the community as a whole tends to have a more engrained duty to ensure the safety of random children on the roads/streets.

What about Vancouver? Can kids that age walk to the park or to the local grocery store by themselves? What about walking to school?

I'm considering letting my kid start exploring themselves around that age but at the same time I'm not sure if Vancouver is as good as where my family was originally from in this regard. Any thoughts?
