Methods: We designed a three-arm pragmatic randomized controlled trial. Eligible participants will be randomly allocated to receive one of three program of care: 1) the "Soft Tissue Injury Care Model" designed by AVIVA Canada;2) the "Pre-approved Framework Guideline for Grade I and II Whiplash Associated Disorders" recommended by the Financial Services Commission of Ontario ; or 3) a physician-based "Education and Activation" intervention.
