Castor was established in 2006 by Brian Richer, a trained architectural stone carver with a degree in English literature and philosophy, and Kei Ng, a trained architect with a background in set design. Richer and Ng are interested in finding the middle ground between art and design in each of their projects, including custom lighting and furniture design and public art commissions. Castor Design has launched a range of products found throughout North America, Europe, Japan and Hong Kong. The founders' experience in restaurants and their love of food and music inspired them to open Parts & Labour in Toronto, a space that combines a fine dining room with a punk rock basement venue. Richer and Ng followed this by founding its offshoot, P&L Burger.
