OPUS & Cie - employees

How it works

Companies joining the program agree to contribute financially to the purchase of OPUS & Cie subscriptions by their employees. In return, the STM agrees to match that discount, up to a maximum of 10%.

Note: OPUS & Cie is only available for full fare monthly passes.

Who's participating?

Near 300 businesses have chosen to join the program since it was first launched.

Advantages for employees

As the employee of a company taking part in the OPUS & Cie program, you’ll receive a discount of at least 8.33%, the equivalent of one free month of transit use.

Your employer can decide to raise the minimum discount and give you even more:

Example of contributions:
10% by Employer + 10% by STM = more than 2 months of free transportation

You will receive a new OPUS card, free of charge, fully guaranteed against loss or theft.

Avoid standing in line and those extra trips to recharge your OPUS card with the OPUS & Cie program’s automatic debit system.
