The increasing role of provincial administrative sanctions in Canadian impaired driving enforcement.

The object of this study is to document the recent shift in Canadian impaired driving enforcement from federal criminal proceedings to provincial administrative sanctions, examine the deterrent impact of these new administrative measures, and review the numerous legal challenges that they have generated. This article highlights the expanded role of provincial administrative license suspensions (ALSs) and vehicle impoundments (AVIs) in Canadian impaired driving enforcement, summarizes the evidence of their deterrent impact, and discusses the implications of the related Canadian case law. Provincial administrative sanctions have been used increasingly, both to supplement and replace federal impaired driving charges.
