75% of resumes are rejected by Applicant Tracking Systems before any human reads them. This guide explains exactly how ATS works in Canada, why resumes fail, and the specific steps to optimize yours.
An Applicant Tracking System (ATS) is software used by employers to receive, sort, and filter job applications before a recruiter reviews them. In Canada, over 95% of companies with more than 50 employees use an ATS — including all major banks, government departments, tech companies, hospitals, and retailers. The ATS parses each resume into structured data, then scores it against the job description using keyword matching, section detection, and formatting compatibility checks. Resumes that score below the employer's threshold — typically 60–70% match — are automatically moved to a rejected folder. The recruiter never sees them. ATS systems commonly used in Canada include Workday, Taleo, Greenhouse, BambooHR, and iCIMS. Each has slightly different parsing behavior, which is why ATS optimization requires formatting rules that work across all systems, not just one.
Missing keywords
The job posting contains specific terms the ATS searches for. If your resume uses synonyms or different phrasing, it scores lower — even if your experience is identical.
Wrong section headings
ATS parsers look for standard headers like "Work Experience", "Education", and "Skills". Creative headings like "My Journey" or "Where I've Been" confuse parsers and cause data loss.
Tables, columns, and text boxes
Many ATS systems cannot read text inside tables, two-column layouts, headers/footers, or text boxes. Content in these elements becomes invisible to the system.
Non-standard file format
Always submit as a .docx or single-column PDF. Scanned PDFs, image-based PDFs, and heavily designed files often fail to parse correctly.
Missing contact information
ATS systems try to extract name, email, phone, and location from your resume. If these are in a table, header, or unusual position, they may not be captured correctly.
Keywords come directly from the job description. Here is a simple manual method:
Read the job posting and highlight every skill, tool, technology, and qualification mentioned — especially in the requirements section.
Identify which of these terms appear multiple times. Frequency indicates importance to the employer and the ATS.
Check if your resume uses the exact same phrasing. If the posting says "project management" and your resume says "managed projects", add the exact phrase.
Add missing keywords naturally into your work experience bullets, skills section, or professional summary.
Most Canadian ATS systems use a threshold of 60–70% match before a resume is forwarded to a recruiter. However, in competitive markets (tech, finance, government), recruiters may only review the top 10–15% of applications, meaning a score above 80% is needed to stand out. As a rule: never submit a resume with a score below 70%. Use ResumeRadar's ATS optimizer to see your score before you apply.
Not all ATS systems work the same way. Understanding the platform an employer uses helps you optimize correctly.
| ATS System | Used by | Key optimization factor |
|---|---|---|
| Workday | RBC, TD, federal government, Shopify | Section headers must match expected labels exactly |
| Taleo (Oracle) | Air Canada, Bell, large manufacturers | Keyword density + exact phrase matching |
| Greenhouse | Tech companies, startups | Skills section + job title matching |
| iCIMS | Healthcare, universities, mid-size companies | Education section formatting critical |
| SAP SuccessFactors | Enterprise, mining, energy sector | Structured data extraction from standard sections |
✗ Two-column or table layouts
ATS parsers read linearly. Multi-column layouts merge content from different sections.
✗ Headers/footers with contact info
Many ATS systems ignore headers and footers entirely. Put contact info in the main body.
✗ Images, logos, or graphics
ATS cannot extract text from images. Any content in a graphic is invisible to the system.
✗ Non-standard section labels
Use 'Work Experience', not 'My Career'. ATS looks for expected labels.
✗ Saved .docx with tracked changes
Always submit clean files without revision marks. Track changes can confuse parsers.
✗ Text boxes (Word/Canva)
Text boxes are extracted separately or missed entirely. Use standard paragraph text only.
