Drinking too much alcohol always has consequences – in some cases it’s a headache, in others a DUI charge. A charge for driving under intoxication won’t affect your work biography, but a DUI conviction will. As a matter of fact, impaired driving would have a serious impact on your future employment opportunities.
Criminal records are publicly available and your future employer could check on them. There are no laws in Ontario prohibiting people convicted of impaired driving from working in the future, but the decision of whether to accept employment will depend on the view of your prospective employer. Considering possible consequences, the help of a DUI top defense lawyer would never be superfluous.
