ATS Optimization Guide 2026

Last updated: May 2026 · 10 min read

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.

What is an Applicant Tracking System (ATS)?

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.

Why do resumes fail ATS screening?

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.

How to find the right keywords for a job posting

Keywords come directly from the job description. Here is a simple manual method:

1

Read the job posting and highlight every skill, tool, technology, and qualification mentioned — especially in the requirements section.

2

Identify which of these terms appear multiple times. Frequency indicates importance to the employer and the ATS.

3

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.

4

Add missing keywords naturally into your work experience bullets, skills section, or professional summary.

ResumeRadar does this automatically. Paste the job description and ResumeRadar identifies all missing keywords, adds them to your resume in context, and shows you exactly which ones were matched before and after.

ATS formatting rules for Canada

Use a single-column layout
Use standard section headers (Work Experience, Education, Skills)
Submit as .docx or clean PDF
Use standard fonts (Arial, Calibri, Times New Roman)
Use tables or text boxes for content
Use two-column or magazine-style layouts
Put contact info in the document header
Use creative section headings

What ATS score should you aim for?

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.
