Book excerpt: “Canada’s back” announced the victorious Liberal Party in October 2015. After almost ten years of Conservative Party rule, the Harper era in Canadian foreign policy was over, suggesting a return to the priorities of gentler, more cooperative Liberal governments. But was the Harper era really so different? And if so, why? This comprehensive analysis of Canada’s foreign policy during the Harper years addresses these very questions. The chapters, written by leading scholars and analysts of Canadian politics, provide an excellent overview of foreign policy in a number of different policy areas. They also offer differing interpretations as to whether the transition from a minority to majority government in 2011 shaped the way that the Harper Conservatives conceived of, developed, and implemented international policy. The analysis is gripping and the findings surprising, particularly the contention that the government’s shift to majority status was far less important to foreign policy under Harper than it had been under previous governments. The reasons why reveal important insights into the Harper decade of foreign policy.
