Welcome to our building centre: Crosby, Ontario

Crosby Store

In 2011, we opened our store in Crosby on the corner of Hwy 15 & Hwy 42. Our 7,500 sq.ft. drive-through dome makes it very convenient for pick up as that's where most of our lumber is stored. Our 2,700 sq.ft. retail store stocks a wide selection of hardware, plumbing, paint, electrical and seasonal products for your home renovation and building projects - large and small. 

We Deliver

If you don't see what you need when visiting our drive-thru, our yard, our retail store and our online catalog, please let us know - we'll be pleased to source whatever you need! Our trucks deliver FREE to the local area of Crosby. For out-of-town deliveries, ask us for details. From our store, we now serve from Kingston, Gananoque and Brockville to Smith Falls and all the surrounding communities.

Our History

Rideau Lakes Building Centre has been in business since April 8, 2008, when we founded the original lumberyard in Elgin, Ontario and we served the surrounding community until December 2010, when we relocated to our Crosby location.
