Service Lines Warranty company and sewer contractors

Has anyone made a claim for sanitary sewer connection work with Service Lines Warranties of Canada? Does anyone know what companies are the designated contractors for SLWC?

I want to see who does the work in Windsor under this insurance company because they do allow you to pick. If I can find out who and what they are able to do, it would go a long way for my planning. Thank you in advance to all who help.
