Conflict of Interest Rules
Public Health Ontario recognizes that many external advisors may not be completely free of actual, potential or perceived conflict of interest, as they may have affiliations with regulated industries, the scientific community or special interest groups, which receive funding from industry.
In an attempt to avoid or mitigate conflict of interest, we have developed conflict of interest rules that are intended to achieve a reasonable balance of those divergent considerations and the expertise we hope to gain from the external advisors, while avoiding or mitigating conflict of interest. To this end, each candidate will be asked to complete a conflict of interest disclosure form as part of the application process.
