Do You Need a Cover Letter in Calgary? When It's Worth Writing One
November 8, 2026
Most online applications today have a resume upload and nothing else. Plenty of people never send a cover letter and still get interviews. So are they necessary?
Short answer: only when the posting asks for one. Otherwise it depends on the job.
What the surveys say
They disagree. One survey of 450 hiring managers found about four in ten never read cover letters, and about a quarter read every one. Other surveys report that most hiring managers expect one even when it's listed as optional. Many of these come from résumé and job-board companies, so treat the numbers loosely.
The practical takeaway: some readers ignore them, some use them to choose between similar candidates, and you won't know which you've got.
When to write one
The posting asks for it. Skipping a requirement is an easy way to get screened out.
The role involves writing or client contact. Admin, communications, sales and customer-facing roles are where writing quality is part of the job.
Your resume needs context. A career change, a gap, a move to Calgary, or a mismatch between your title and the job. A few sentences can explain what a resume can't. See Applying Without a Perfect Match and Job Hunting as a Newcomer to Calgary.
A small employer is hiring. A real person is likely reading every application.
You're applying to a job you really want. The extra 20 minutes is cheap.
When to skip it
There's no place to attach one and the posting doesn't mention it
High-volume hourly roles where employers screen quickly on availability and experience
You'd be rushing a generic letter. A weak, copy-pasted letter doesn't help you. A strong resume alone is better.
For City of Calgary, AHS and Government of Alberta jobs, each employer has its own application system, so check what each posting asks for. We cover the differences in How to apply to City of Calgary, AHS and Government of Alberta jobs.
If you write one, keep it short
Half a page to one page, around 250 to 350 words.
Opening: the role and why this employer, in one or two sentences. Skip "I am writing to apply for."
Proof: two or three requirements from the posting, each with a specific example of what you did.
Close: say you'd like to talk, and thank them.
Rewrite the middle for every job. If you can't tailor it, don't send it.
No upload field?
Put your two strongest sentences in the summary or "additional information" box, or in the first lines of your resume.
