Margaret Janssen

Paul’s passion for construction was evident from a young age. He worked on construction sites during his high school years and his passion switched to design and architecture. He did his first design, for an addition, for a local contractor at the age of 16. Paul studied Architecture at Ryerson where he obtained his Bachelor of Technology in Architectural Science and studied at Lawrence Tech University for his Bachelor of Architecture. He started his construction company at the age of 24 and married his highschool sweetheart the same year.

JDC has won the Business Excellence Awards for Home Builder Excellence several times, is a board member of the local Board of Trade, a member of Tarion, RenoMark and Paul is the president of the Greater Dufferin Home Builders’ Association for the second time in his career in 2019-2021. As you can tell, Paul is a firm believer in giving back to the community in which they live and work and has extreme pleasure in participating in local community events.

Margaret is the glue (better than carpenter’s glue) that holds the company together. Growing up with family members in the construction industry and with post-secondary administrative training, her knowledge is critical in keeping things running smoothly from day to day. She allows the construction team to focus on all aspects of the work site while she manages the, ever important, work in the office.
