Registration for Activities

Online registration for activities is recommended. Only payments by credit card (Visa or Mastercard) are accepted, and a resident’s card is required.

Activities are free for residents, unless otherwise indicated. Online registration is mandatory for most activities. It is important to create your account* in advance on the registration platform in order to access this feature. Please allow 48 business hours for account approval. During registration periods, this timeframe may be extended to up to 72 hours due to the high volume of requests.

Registration by phone is also available for individuals who do not have access to a computer (450-455-3371). The Citizen Card is the only accepted proof of residency.

*Before creating an account, please first check whether you already have an active account on the platform by selecting “Forgot Password.” This step will help speed up the registration process for everyone. Thank you for your cooperation.
