The risks of smoking could soon include a $5,000 fine for those who light up within nine metres of Ottawa bus stops.

The City of Ottawa's public transit company, OC Transpo, launched a public education campaign at a news conference Thursday to ensure smokers know about the rules and to announce that it will begin enforcing them.

Those who violate a ban on smoking in bus shelters or within nine metres of a bus stop could start getting fines of $150 to $5,000 in the new year.

However, OC Transpo officials said they might shrink the smoke-free radiusĀ at some bus stops that don't have much space around them.

The city also announced Thursday that smokers who want to quit can get free nicotine replacement therapy by enrolling in a study run by the Centre for Addiction and Mental Health (CAMH), the Ministry of Health Promotion, and Ottawa Public Health.
