Special fare $1


When the smog warning is given, late afternoon for the next day by Environment Canada, the STL sets in motion the Smog Alert process and the $1 unit pass will be valid all day the next day, on all of its regular network of buses and shared taxis.

Exemple : Smog warning on September 26th at 5 pm for the next day → $1 single fare all day September 27th

Due to the preparation time of our fleet and our staff, the STL can not react immediately to changing environmental conditions.

By offering the Laval population a reduced rate, the STL is making a real contribution to improving air quality and encouraging more people to take public transit.

This unique initiative in Canada runs from June 1st to Labor Day.
