Notice vs. filing
Two separate things have to happen. First, you notify your employer of the injury, in writing, within 30 days. Second, you file your own claim with the Workers’ Compensation Board using Form C-3, the Employee Claim. Telling your employer does not file your claim, and assuming it does is a common mistake.
Form C-3 is your formal request that the Board open and decide your case. It identifies you, your employer, how the injury happened, and the body parts affected.
How and when to file
You can file Form C-3 with the Board online through its web portal, by mail or email, or in person. It cannot be filed by telephone, although the Board’s customer service line can help you. Filing online is generally the fastest and gives you a record of submission.
The deadline is generous compared with the notice rule: you generally have up to two years from the date of the accident – or from when you knew a condition was work-related – to file. Filing sooner is still better, because evidence and memories are fresher.
Filling it out well
Be specific and consistent. Describe how the injury happened in plain terms, list every body part affected even if one hurts more than another, and make sure the details match what you told your doctor and employer.
After you file, the Board assigns a case number and notifies the employer’s insurer, which must then respond. Keep your copy and the case number – you will use it to track the claim.
