Cannabis and work: rules to follow

Hydro-Québec's suppliers and their sub-contractors must all undertake to promote a drug- and alcohol-free work environment and comply with the Hydro-Québec Supplier Code of Conduct.

Consult the Supplier Code of Conduct

No cannabis symbol

Our health and safety requirements and practices for requests for proposals (RFPs) and contracts have changed. Please consult them.

We believe that no economic incentive justifies endangering the health and lives of our employees and suppliers. As a result, we are making a concerted effort to improve workplace health and safety and aim on setting the standard in this field.

Rest assured that you can count on our cooperation for the implementation of these new practices.

Changes and important reminders...

...for suppliers of Hydro-Québec and Société d'énergie de la Baie-James (SEBJ) to ensure that your invoices are processed efficiently.

Integrity in Public Contracts Act

Since November 2nd, 2015, the threshold for public services contracts and subcontracts for which enterprises have to obtain a prior authorization from the Autorité des marchés financiers (AMF) decreased from $5 million to $1 million. Note that the reduced threshold is only applied to service contracts. Therefore, construction contracts have not been affected and their threshold is set at $5 million. The calculation of these applicable thresholds includes the amount of the expenditure that would be incurred if all renewal options were exercised.

For more information, please visit the AMF Web site at the following address:
