Community and the environment is important to the entire team at Muskoka Rock. We are a group of like-minded individuals bringing a shared commitment to the entire Muskoka Region, the communities we live in, the quarries our granite is produced in and our team of staff that work for our entire organization. Commitment to our community, the environment and our team is a leading value of our organization.

At our picturesque quarries we produce our Muskoka granite with purpose, creating as little waste as possible. As we look towards the next generation our quarries will continue to adhere to the highest Ontario and Canadian standards, benefiting all of Muskoka responsible way.


We are extremely pleased to see the Hall and Coulson teams join forces to create this new product to an age old industry and approach this business in a unique methodology by incorporating technology into the business side of the product. We will have a new source of purchasing treads and flagstone in a wider selection of colours than locally available to add a new level of customization to our projects. We can now match much more closely the native stone of our project with the stone available at the MRock production facility and can order dimensional product for unique situations.

Chris Madden, President, Tamarack North Ltd.

Our Company, Red Sky Custom Builders, have used the custom cut stone available through the Muskoka Rock Company to create unique and innovative results for our clients.  We can now order custom-cut granite such as mantels, steps and flag, all in unique shapes, sizes and depth while retaining a natural look.  The possibilities are endless since we can order natural stone to adapt to any application that we may have. MRock is true Muskoka/Parry Sound product with a range of colours depending on which quarry the stone is sourced from.  You and/or your clients will be impressed with MRock.

Joel L’Ecuyer Red Sky Custom Builders

In the  building of our cottage, we wanted to preserve the integrity of our site and harvested some of our own granite from our site to be used as stone in our landscape and patio work. MRC went the extra mile, not just to provide customer service, but to also fully understand how the end product should look and work.  Without them I doubt we could have captured the look and feel that we wanted. We are proud to endorse them and their products.

Are all projects custom or do you have inventory?

Although we take great pride in our ability to produce custom granite materials, to spec, on demand, we do have an extensive inventory of flooring, building stone, flagstone and stair tread products on site. Give us a call or stop by our office and plant for details.

Will you deliver my order?

Absolutely. We will gladly deliver or arrange delivery on any order.

What is the thinnest and thickest you can cut a piece of granite?

Granite can be cut to a minimum thickness of 1/2″ while the maximum thickness is only restricted by the size of the boulders on hand.

Do you offer installation service for Muskoka Rock Company products?

Although MRock does not perform installation, we are glad to recommend expert installation services offered by our installation partners.
