Inadmissibility applies to everyone included in the application to Canada. The entire application and all family included will be refused if there are criminal or medical inadmissibility issues with just one member. Though inadmissibility is a barrier to immigrating to Canada, there are ways to overcome it and be allowed to immigrate Canada.
If a person has been convicted of a crime, or committed a crime in their home country the person may be considered inadmissible to Canada due to criminality.
It is important to note that not all crimes and convictions make a
person inadmissible to Canada. The crime has to be of a certain degree of seriousness.
