ATS systems reject resumes for formatting errors most people never notice. Here are the 10 biggest mistakes β and exactly how to fix each one for Canada and USA jobs.
Your resume could be perfectly written β strong experience, great keywords, compelling achievements β and still never reach a human recruiter. The reason? A formatting mistake the ATS can't read.
In Canada and the United States, over 95% of mid-to-large employers use Applicant Tracking Systems to filter applications automatically. These systems don't think β they parse. And when your resume formatting confuses the parser, your content disappears, your score drops, and your application gets archived before anyone reads a word.
Here are the 10 formatting mistakes that trip up ATS systems every day β and exactly how to fix each one.
Two-column resume templates look sleek in design apps. But ATS parsers read left to right, top to bottom β like a text file. A two-column layout causes the system to mix content from different sections, scrambling your job titles, dates, and skills into unreadable data.
Fix: Use a single-column layout only. Every section flows top to bottom. No exceptions.
Many resume templates place your name, phone, and email inside a Word document header. Most ATS platforms cannot read content in headers or footers. Your contact information simply doesn't get captured β meaning no one can call you even if your resume makes it through.
Fix: Place all contact details β name, phone, email, LinkedIn, city β at the top of the main document body.
Tables are a common way to create clean side-by-side layouts. ATS parsers handle tables poorly β content inside cells is often misread, merged with adjacent cells, or skipped entirely. Your skills section may simply vanish from the parsed data.
Fix: List skills as plain text, comma-separated or one per line. No tables anywhere in the document.
PDF is not universally safe. Older ATS platforms β including Taleo, which is widely used by large Canadian and US corporations β struggle to parse PDFs accurately, especially those created from design software. Content gets skipped or the parser fails entirely.
Fix: Default to .docx unless the job posting specifically requests PDF. DOCX is universally compatible with every major ATS.
Profile photos, skill rating icons, logos of past employers, and decorative elements are completely invisible to ATS parsers. The system skips them entirely. Any information contained in or near those graphics may not be captured at all.
Fix: Remove every image and graphic. Replace visual skill ratings with plain text β "French: Professional working proficiency."

Fix: Use only standard, conventional section headings throughout your resume.
Decorative fonts, symbols used as bullet points (β β¦ β ), and special Unicode characters often fail to render correctly inside ATS systems. The parser may produce garbled text or question marks where your carefully chosen symbols appeared.
Fix: Use standard fonts (Calibri, Arial, Georgia, Times New Roman) at 10β12pt. Use standard round bullet points only.
Word's text box feature is commonly used to position content visually. ATS parsers treat text boxes like invisible objects. Any content inside a text box is typically not extracted during parsing β it simply disappears.
Fix: Remove all text boxes. Move the content directly into the main document body as standard paragraph text.
ATS systems calculate your years of experience from the dates in your work history. If your date format is unusual or inconsistent β "2019β'22" or "2020/03" β the parser may misread them and calculate your experience incorrectly, potentially disqualifying you from roles you're qualified for.
Fix: Use consistent, standard date formats: "January 2020 β March 2022" or "Jan 2020 β Mar 2022" throughout.
File names like "resume_FINAL_v3_USE THIS ONE.docx" look unprofessional in ATS systems and recruiter inboxes. Some platforms display the file name exactly as submitted to hiring managers β first impressions start before anyone opens the document.
Fix: Save as: FirstName-LastName-Resume.docx (e.g. Sarah-Johnson-Resume.docx). Clean, professional, unambiguous.
"A well-written resume with poor formatting scores lower than a mediocre resume with clean formatting. The machine reads the structure first."

All 10 mistakes above apply equally to Canadian resumes. Canadian employers use the same ATS platforms as US companies β Workday, Greenhouse, iCIMS β so the formatting rules are identical.
If you're applying to bilingual roles in Quebec, include both English and French versions of key skills and certifications. Some Canadian ATS setups are configured to search in both languages, increasing your keyword match rate. Also β never include a photo on a Canadian resume, regardless of what your template suggests.
