Practices of finding a job in Canada may not be the same as in your home country. And an important practice in Canada is to submit a cover letter along with your resume for all job applications.
It takes time and effort to put together a customised cover letter for each job application. When I was applying for jobs, I sometimes got lazy and skipped this step. But do this at the risk for not being called for an interview. This is not to say that you will never be called for an interview if you don’t submit a cover letter. But my point is, why take the risk. So take the time to put together a customised cover letter. You never know, it may turn out to be the best-selling point for your resume to get shortlisted.
