For access to the métro

  • Use STM-owned entrances and exits. Some entrances to our stations are in buildings that are not ours. These businesses and services may refuse your dog entry. 
  • Dogs are not allowed at the Longueuil-Université-de-Sherbrooke station because the entrances do not belong to STM. 

If you break the rules

The rules are in place to keep you and others safe. 

Failure to comply could result in a fine ranging from $75 to $500.

See the regulations on safety and behaviour standards in rolling stock and buildings operated by or for the Société de transport de Montréal
