What is the legal age a minor child can ride public transit alone in Alberta Canada?

In Alberta, Canada, there is no specific legal age at which a minor child can ride public transit alone; instead, it is generally at the discretion of parents or guardians to determine if their child is mature enough to do so. Transit authorities may recommend that children under a certain age, often around 12, be accompanied by an adult. Parents should consider their child's maturity and ability to navigate public transit safely before allowing them to ride alone.
