Muskoka Disposal Services Limited (MDSL) is a recent addition to the Coulson Brothers family. MDSL is a multi-purpose disposal service company, with various bin sizes to suit any need. With MDSL we can deliver 14, 20, and 40 yard bins to your job site. These bins can be barged to anywhere, allowing almost anything to be removed from your island or lakefront property. MDSL now has a licensed vacuum pump allowing sewage to be pumped up and taken away for disposal. In league with MDSL, Coulson Brothers can deliver a more complete service for the disposing of waste.
