John McLellan receives an award of recognition from Big Brothers Big Sisters Oshawa-Whitby chapter for their continued support.

John McLellan is the owner of McLellan Contracting and a GAF Master Elite® certified contractor—a distinction held by only the top 2% of roofing contractors in North America. This elite status enables him to offer industry-leading 50-year material and labor warranties, plus 25 years of workmanship coverage that standard contractors cannot provide. With over two decades of experience, John has built his business on quality workmanship, manufacturer-backed warranties, and transparent pricing. He ensures his entire team completes a minimum of five days of certified training annually through GAF and other industry programs—a significant commitment in an industry where 94% of roofers have never had formal training.
To maintain Master Elite certification, John's company must requalify annually, meeting rigorous standards for training credits, installation volume, and customer satisfaction. His detailed, itemized quotes help homeowners understand exactly what components protect their investment and why proper installation matters. A vocal advocate for consumer protection, John educates homeowners about the critical differences between minimum code compliance and best practices. McLellan Contracting serves the Durham Region and surrounding communities, bringing professional installation standards and manufacturer-backed peace of mind to every project..
