Some people ask, “So who is TWD and what do you do?”.  Sure, we are a mid-sized Canadian EPCM firm in business for around 20 years now, but more importantly we would want you to know that we simply love the challenge of working together to deliver!  What makes things even more magical at TWD occurs when we combine this underlying characteristic with our desire to responsibly and respectfully support a growing world, it becomes our passion and our WHY.
