While it’s not a requirement to have work experience if you wish to work as a truck driver in Canada, having work experience can increase your chances of a successful application to certain immigration programs. If you’re applying for Express Entry, having previous work experience in the field you wish to work in can increase your chances of being successful.
The IRCC usually uses the NOC (National Occupation Classification) to evaluate how the work experience of a given immigration candidate will support the requirements of the immigration program they are applying for.
