Who We Are


The Sheldon Group is home to a multidisciplinary team of Scientific Research and Experimental Development (SR&ED) tax practitioners, accountants, technical writers and litigators with many decades of collective experience in the preparation, submission and defense of SR&ED claims in all industries and provinces throughout Canada.

Our Mission

We seek to acknowledge organizations bettering the world through technological and scientific advancement.

As Canada’s premiere Scientific Research and Experimental Development (SR&ED) advisory firm, our goal is to assist Canadian companies across diverse fields to continue to advance technology through support provided by the SR&ED program. We wish to assist companies to receive the refund they are entitled to in Canadian law through our vast experience in preparing and defending SR&ED submissions.
