COVID-19 update

IMPORTANT MESSAGE, March 19th 2020:

Dear clients, families and partners,

Due to the recent situation regarding COVID-19, our office doors have been closed as of Tuesday March 17th 2020 until Monday April 6th 2020, unless otherwise noted.

You can connect with Service Coordination Support, including DSOER, by calling at 613-748-1788 or 1-855-376-3737. We will be monitoring the messages on the SCS and DSOER voicemails on a regular basis throughout the day. You can also connect with your worker directly by leaving them a message on their individual voicemail and they will prioritize your call within the next three business days.

Staff are directed to replace “in-person” meetings with telephone or online communications. If you require information about services or assistance completing forms (including ASD respite funding forms), please leave a message at 613-748-1788 and a staff will return your call within three business days to help you.

Additional cancellations:

  • All community presentations are cancelled until further notice.
  • No drop-ins will be accepted by SCS including DSOER, until further notice.

We will continue to monitor the status of the situation, and will update this message as updates become available.

Thank you,
Service Coordination Support for People with Developmental Disabilities

MCCSS Compliance

DSO SCS was found to be in compliance with Ontario Regulation 299/10 of SIPDDA (Quality Assurance Measures) and/or policy directives applicable to MCCSS-funded services and supports for adults with developmental disabilities.
