We are a 3rd generation family owned and operated business that has been serving the lakes of Muskoka since 1969. With five barges, Coulson Bros. has the largest operating capacity on Muskoka Lakes. With over 45 years of experience, we offer a wide variety of services for your water access property.

Lately our company has begun to expand moving into different fields of work. The newest branch of Coulson Bros. is called Muskoka Disposal Services Limited (MDSL). MDSL is an all around disposal service, carrying various sized containers for any debris. MDSL is equipped with a 3000 gallon vacuum pump tank for sewage removal on water access properties.

Through the years our certified weld shop has let us design customized equipment for a low environmental impact on delicate shoreline properties.

At Coulson Bros. Scow Service we make it easy for you to plan your deliveries for supplies ANY time of year! We serve Lakes Muskoka, Rosseau and Joseph year round.

Summer barging is an ideal way to supply remote locations with everything from household goods and building materials (right up to transporting your hot tub and bringing the crane to install it!) . We’ve even hauled massive heavy machinery well over 170,000 lbs. and 30′ long.

For some clients, we haul their equipment to the site at the end of summer so we’re ready to get straight to work on freeze up.

There are virtually no size or weight limits on what we can barge for you.
