If you have been charged with impaired driving, “over 80” or refusal or failure to blow, then you may have already realized that this is one of the most complex areas of criminal law. The good news: many impaired driving cases have the potential for success. As both skilled defenders and former Crown prosecutors, we offer you the distinct advantage of our experience representing both sides in these matters. Our thorough understanding of the rules and procedures involved in impaired driving law can help you avoid a conviction and get your drivers licence back.

First Steps

Take these three steps to begin preparing your defence:

  1. Call Chris Archer at 403-237-9200 to set up a free consultation.
  2. Write an objective and detailed account of the entire day in question. Leave out nothing. It could be more than 6 months before you go to trial; by then, your memory will have faded and you will need your written statement to remind you of the circumstances leading up to and following your being charged.
  3. Do not speak to the police or the prosecutor without your lawyer.
