September 2019: From metros to mines, hydropower, and beyond, the Canadian underground construction sector has a vibrant past. A new book from the Tunnelling Association of Canada (TAC), which will mark its 40 anniversary in 2020, will celebrate this long history from the early pioneer work that built the country to landmark projects of recent years, such as the Canada Line in Vancouver. Erik Eberhardt, President of TAC, and Rick Lovat, Past President of TAC, speak about the vision of the book and explain what makes the Canadian underground sector special.
