The council outlined 13 recommendations, including the creation of the Canada Infrastructure Bank, the launch of a re-skilling program for the Canadian workforce, the formulation of growth strategies for sectors with untapped potential, including agriculture, and the development of the Invest in Canada hub.

Ambassador of Canada to China On 4 September 2019, Barton was appointed to be ambassador to China by the Government of Canada. The appointment was met with a mixed reaction, including scrutiny around Barton's past ties with China while proponents of the appointment argued that Barton's Asian and Chinese experience made him a uniquely qualified selection. After taking on the role, Barton led Canada's efforts to win the
release of Michael Kovrig and Michael Spavor, two Canadians who were imprisoned in China in December, 2018, in a move widely seen as retaliation for the arrest of Huawei executive Meng Wanzhou. Throughout their detention, Barton conducted regular consular visits with Kovrig and Spavor, often delivering coded messages to avoid interception from eavesdropping prison guards. The Toronto Star also reported that Barton's work on this file pre-dated his appointment as Ambassador, as his network and understanding of the relevant stakeholders helped pave the way for open communication channels between Chinese, Canadian, and U.S. officials. In April 2021, this included meetings in Washington where Barton received a commitment from senior U.S. officials to put intensity into their pressure on Beijing. The Wall Street Journal also reported that Barton maintained a line of communications with Xie Feng, China's Vice Foreign Minister, to coordinate the logistics of an eventual resolution that would bring the prisoner standoff to an end. It was reported by Canadian media that this flight followed weeks of consecutive meetings held with Barton and Chinese officials as part of a "highly choreographed" effort. On December 6, 2021, it was announced that Barton would step down from the role after completing the "core mission" that he had been appointed to achieve: securing the release of Kovrig and Spavor.
Writing Barton is the author of
China Vignettes: An Inside Look At China. Barton led a research team that conducted interviews with ordinary Chinese citizens and captures his findings with a series of short stories about daily life. Barton is the co-author of
Dangerous Markets: Managing in Financial Crises. This book lays out a plan for global business leaders to manage their organizations through hazardous economic environments, providing advice to executives on how to navigate increasingly volatile financial markets. He also co-authored
Re-Imagining Capitalism, which looks at capitalism through a contemporary lens and ponders how the economic system might be adapted to modern times. The book argues that the focus of capitalism should be expanded and adapted to focus more on long-termism.
Re-Imagining Capitalism builds on Barton's previous writing, which reflects on the
2008 financial crisis, rejecting the "false choice" between serving stakeholders and shareholders while advocating for long-term planning from business leaders. Most recently, Barton co-authored
Talent Wins: The New Playbook for Putting People First, which argues that the primary driver of long-term success in companies is talent. The book maintains that business executives and leaders need to develop and manage their human capital even more intensely than they do their financial capital.
