Drummond was Senior Vice President and Chief Economist for the TD Bank from 2000 to 2010. He led TD Economics' work in analyzing and forecasting economic performance in Canada and abroad. From 2001 until his retirement, he headed government relations for the bank. He was regarded as having transformed the bank's economics department into a "
think-tank on topics of national importance". Many of Drummond's reports at TD were credited with significantly influencing government's policy decisions, including the reported impact of his 2008 report "Time for a vision of Ontario's economy" (co-authored with Derek Burleton) in shaping the 2009 Ontario Budget and convincing the provincial government to harmonize its
sales tax with the federal Goods and Services Tax. During this tenure at TD, he participated in a variety of public policy initiatives, including serving as an advisory panel member of
Bob Rae's review of Ontario post-secondary education (the "
Rae Report"), serving on the Task Force for Modernizing Income Security for Working-Age Adults of the Toronto City Summit Alliance (now, the
Greater Toronto CivicAction Alliance), chairing the Labour Market Ministers’ Advisory Panel on Labour Market Information, and co-chairing a Toronto Financial Services Alliance Working Group to establish a global risk management institute in Canada. Drummond also served as a member of the
National Statistics Council and was openly critical of the federal government's 2010 decision to eliminate the long-form census for the
Canada 2011 Census without consulting the advisory body. In July 2010, he testified to the
Canadian House of Commons Standing Committee on Industry, Science and Technology on the planned replacement of the mandatory long-form with a voluntary National Household Survey, stating: "I think the data could actually be worse than not having anything. It could be misleading. You may be making misleading inferences because you don't actually know how to properly weight the groups that might be underrepresented." == Fellowship at Queen's University ==
