The Globe and Mail reports in its Wednesday edition that Canada's oil and gas sector faces risks of a return to painful cost overruns unless it co-ordinates the necessary supply chains and labour availability for more than $100-billion in proposed energy infrastructure construction. The Globe's Emma Graney writes that the warning comes from RBC, which said in a report, "Canada is about to find out whether it can still build." Getting major projects constructed has been one of Prime Minister Mark Carney's highest priorities, as the country looks to reduce its reliance on the United States. In September, the feds tabled Bill C-39, the Building Canada Strong Act, which in part aims to speed up development approvals for major projects. Mr. Carney also announced a corporate tax break that would allow companies to immediately write off the full cost of acquiring or building assets. The last oil sands construction boom ran between 2006 and 2014; labour and materials costs soared as several projects were built at once, leading to overruns and delays on everything from mines to pipelines. Enabling domestic capacity of steel and aluminum production will be "critical to optimizing the benefits of energy investment," RBC said.
