- Criminal Inadmissibility such as driving while being impaired (DWI) or driving under influence (DUI).
- Medical Inadmissibility which refers to an individual being medically inadmissible to Canada if their condition poses a threat to the health/safety of the Canadian public. However, not all temporary residents are required to be medically examined. It only applies to those who wish to stay in Canada for more than six months. Although exceptions also apply to those coming for less than six months.
- Non- Compliance which consists of individuals failing to act in accordance to the citizenship and immigration Canada manual. For instance, entering Canada to study without a study permit or entering to work without a work permit.
The list continues and includes other reasons due to which entry may be denied. However there are ways to overcome such situations/inadmissibility; a temporary resident permit or an application for criminal rehabilitation.
