Frequently Asked Questions
What is the difference between an IRS and a criminal DUI charge in Alberta?
An Immediate Roadside Sanction (IRS) is an administrative penalty levied by the province of Alberta, resulting in immediate licence suspension and fines. A criminal DUI is a separate federal charge under the Criminal Code of Canada. A specialised lawyer can help you appeal the IRS while simultaneously defending your criminal charge.
How much does a DUI lawyer typically cost in Calgary?
Most reputable criminal defence lawyers work on a block fee basis rather than hourly billing for impaired driving cases. Depending on the complexity of the trial and the seniority of the lawyer, you can expect to pay anywhere from $3,500 to over $10,000. Always ensure the firm is transparent about costs upfront.
Can impaired driving charges be dropped before trial?
Yes. Skilled lawyers—like many featured on our list—can frequently negotiate with the Crown Prosecutor to have charges withdrawn or reduced to lesser traffic infractions if they identify significant procedural errors, Charter rights violations, or flaws in breathalyser calibration.
