"Cover letters are dead."
"Always write a cover letter."
"Nobody reads them."
"They read mine before my resume!"
You've heard all of this. And somehow, everyone is correct.
Welcome to the most confusing document in your job search. Let's cut through the noise with actual data.
The Paradox: Schrödinger's Cover Letter
Here's what the research actually says:
| Finding | Source |
|---|---|
| 83% of hiring managers read cover letters even when optional | Interview Guys, 2025 |
| 45% read cover letters BEFORE looking at resumes | Interview Guys, 2025 |
| 40% of HR professionals never read cover letters at all | Novorésumé Survey, 2025 |
| 66% spend less than 30 seconds on a cover letter | SecondTalent, 2026 |
| One recruiter: "Read 100K+ resumes, maybe 50 cover letters" | LinkedIn, 2025 |
Sources: Novorésumé HR Survey, Interview Guys 2025 Report
So which is it? Both. And that's exactly why you need a strategy, not a blanket rule.
The Critical Question: When Does It Actually Matter?
After analyzing data from multiple surveys and hiring manager feedback, here's when cover letters move the needle:
High Impact (Worth 30+ Minutes)
| Scenario | Why It Matters |
|---|---|
| Startup or small company (<100 employees) | Founder/hiring manager reads every application personally |
| Referral or warm intro | Your connection vouched for youâexplain why you're worth it |
| Career switch | Resume doesn't tell the full story |
| Non-obvious fit | You need to explain why a physics PhD wants a frontend role |
| Company specifically asks | They're screening for effort and communication |
Low Impact (Skip or Use Template)
| Scenario | Why It's a Waste |
|---|---|
| Big tech (Google, Amazon, etc.) | ATS + high volume = nobody reads it |
| Mass applications (100+/week) | ROI doesn't justify time investment |
| Job posting says "optional" | At large companies, optional means "we won't read it" |
| Your resume already tells the story | Senior dev with perfect keyword match? Resume is enough |
The 2026 Twist: AI Made Cover Letters Matter Again
Here's the irony: Everyone thought AI would kill cover letters. Instead, it made them more valuable.
The "AI Slop" Problem
According to Moving2Canada's 2026 report:
"Recruiters report being flooded with cover letters that look polished, keyword-rich, and completely interchangeable."
When 500 applicants submit AI-generated cover letters that all sound the same, the one that sounds human stands out.
What This Means for You
The bar has shifted. It's no longer: - Old bar: Did you write a cover letter? â - New bar: Does your cover letter sound like a human with a point of view?
The Canadian Context: What's Different Here?
Canada's job market in 2025-2026 has shifted back to an employer's market:
| Trend | Impact on Cover Letters |
|---|---|
| Job vacancies down from post-pandemic peak | More competition = need to differentiate |
| Hundreds of applications per posting | Anything that helps you stand out matters |
| International candidates competing | Cover letter can address work authorization proactively |

If you're competing against 500 other applicants, your well-crafted resume gets you past the ATS. Your cover letter gets you remembered.
What Actually Works (And What Doesn't)
The 3 Things Hiring Managers Actually Care About
Based on survey data from hiring managers:
- Why this company (not generic "I'm passionate about technology")
- Why this role (specific connection to your experience)
- What you'll contribute (not what you'll learn)
What They Hate
| Don't Do This | Why It Fails |
|---|---|
| "I am a hardworking team player" | Generic. Everyone says this. |
| Repeating your resume in paragraph form | Adds no new information |
| "Dear Sir or Madam" | Shows you didn't research |
| 3+ paragraphs of text | Nobody reads that much |
| Focusing on what YOU want | They care about what THEY need |
The Speed-Optimized Approach
Here's a practical system for the Canadian tech job market:
Tier 1: Full Custom (30-45 min)
When: Dream companies, referrals, career pivots
Format:
Para 1: Hook + Why this company specifically (1-2 sentences)
Para 2: Your most relevant achievement with metrics
Para 3: How you'll contribute + call to action
Example opening:
When I saw that Shopify is rebuilding its checkout infrastructure, I immediately thought of my experience reducing Stripe payment failures by 23% at [Previous Company]. Here's why I'd be a great fit for this exact challenge.
Tier 2: Template + Customize (10-15 min)
When: Good-fit companies, required cover letters
Keep a base template and swap: - Company name and why you're interested (research 5 min) - Most relevant 2-3 achievements for THIS role - Specific tech stack mentioned in posting
Tier 3: Skip It
When: Mass applications, optional at large companies, resume is a perfect match
Your time is better spent: - Tailoring your resume keywords - Applying to more positions - Building your GitHub portfolio
For New Grads: Projects Are Your Secret Weapon
Don't have work experience? Your cover letter is where you explain WHY your projects matter:
Weak:
I built an e-commerce platform using React and Node.js.
Strong:
My e-commerce platform handles 1000+ concurrent users on AWSâI learned more about scaling from that one "server on fire" moment than from any textbook. I'm excited to bring that scrappiness to Wealthsimple's infrastructure team.
See the difference? The second one shows personality, specific learning, and connects to their needs.
The LetterGen Shortcut
Writing customized cover letters for every application is exhausting. Here's a tool that can help:
LetterGen.io uses AI to generate tailored cover letters based on your resume and the job descriptionâbut with a human-sounding output that avoids the "AI slop" problem.
Use code Hanzi20 for 20% off if you decide to try it.
Disclosure: This is a referral link from a friend who built the tool. I recommend it because it solves a real problem.
When to use it: - Tier 2 applications where you need a cover letter but can't spend 45 minutes - As a starting point that you then personalize - When you're applying to 10+ jobs per week
Canada-Specific Tips
If You're an International Student
Your cover letter should proactively address: - Work authorization status (PGWP, study permit with work rights) - Timeline (when you graduate, when you can start) - Language proficiency (especially for Quebec)
Example:
I'm currently completing my CS degree at UBC and hold a study permit with full work authorization. After graduation in May, I'll transition to a 3-year PGWP, providing stable long-term work eligibility.

For Montreal/Quebec Roles
Mention French proficiency if you have itâeven intermediate level matters:
While my primary work language is English, I have intermediate French proficiency and am committed to improving through immersion.
The Template That Actually Works
Here's a template based on what hiring managers say they want:
Hi [Hiring Manager Name or "Hiring Team"],
[1 sentence: Specific reason you're excited about THIS companyâsomething
from their blog, product, or recent news]
[2-3 sentences: Your most relevant achievement with a metric, connected
directly to what they're looking for]
[1-2 sentences: What you'll bring + enthusiasm for the specific role]
[1 sentence: Call to actionâavailable for interview, portfolio link, etc.]
Best,
[Your Name]
Total length: 100-150 words. That's it.
FAQ
Do Canadian employers expect cover letters?
It depends on company size. Startups and mid-size companies often read them carefully. Large tech companies (Shopify, Amazon, Google) rarely do unless specifically requested.
Can I use AI to write my cover letter?
Yes, but don't submit raw AI output. Use it as a starting point, then add specific details and your actual voice. Hiring managers are increasingly skilled at spotting generic AI content.
Should I address gaps in my resume?
Yesâbriefly. One sentence explaining a gap is better than leaving them to wonder. "I took 6 months to care for a family member" is fine.
What if I don't know the hiring manager's name?
"Hi [Company] Team" or "Hi Hiring Team" is fine. Don't use "Dear Sir or Madam"âit's outdated and assumes gender.
Is a cover letter worth it for remote applications?
For remote roles at companies outside your local area, yesâyou need to explain why you're interested in THEM specifically despite the distance.
Key Takeaways
- Cover letters matter for ~60% of applications, not 100%âknow when to invest time
- AI has raised the barâgeneric letters are now filtered out mentally
- Keep it shortâ100-150 words max, 3 paragraphs
- Be specificâmention the company name, recent news, or specific role details
- For mass applicationsâuse a tool like LetterGen (code:
Hanzi20) as a starting point - New gradsâuse cover letters to explain project context and passion
