Removing a road closure that isn't real

I have a problem where a large section of my drive to work is marked as closed for the last week along Highway 6 in Ontario, Canada from Caledonia to Hagersville. I have found the closure in the Map Editor and it say that it applies from May 7 to Dec 22, 2018 for construction. There currently are not even any construction signs on the road. The Map Editor says that I need to be Level 4 to remove the closure (I am Level 1). There are also 5 or so reports from Waze users saying that the closure is incorrect. How can I get a message to someone to remove this road closure?

This has been removed. The closure was erroneously placed by a local CCP partner. The intention is to have only lane closures and not full closures. Thanks.
