Commentary on population health intervention research.

This commentary discusses the importance of the Pan-Canadian Public Health Network in facilitating the coordination and infrastructure of Canada's public health system. Within Canada, effective intervention practice and research is at the forefront of public health, but there are questions regarding how best to conduct population health intervention research, how to put the evidence into practice and where the necessary resources will come from. These issues are presented using Canadian examples drawn from public health practice, research and policy in the British Columbia context. Sustained and persistent collaboration regarding population health intervention research among Canadian public health practitioners, researchers and policymakers akin to PHIRIC's mandate will better position Canada's public health system to respond to public health issues.
