Abstract
Canada’s Tri-Council Policy Statement: Ethical conduct for research involving humans, first published in 1998, has recently been updated.1 The US Department of Health and Human Services has just issued an Advance Notice of Proposed Rulemaking that would substantially change the 20-year-old Common Rule governing most federally funded research involving human participants.2 A comparison of the two countries’ systems for protecting human research participants is therefore timely. This analysis situates the Canadian system in an international context, with particular attention to its similarities and differences to the US system and their shared challenges going forward with their changes.
