The Ultimate Guide to Arguing with WCB and Coming Out on Top
If WCB makes a decision that you disagree with, there are specific things you want to do to improve your chances of winning a WCB appeal. You don’t have to be a lawyer to appeal a WCB claim and you don’t need to be an expert. All you need is some guidance and even if this is your first appeal, you can be successful.
I get HSE managers, Human Resource, and Business professionals calling me all the time afraid and frustrated because they want to appeal a claims decision but don’t know how. They lack the confidence to challenge a workers’ comp decision for one reason or another.
You don’t need a WCB expert, but you do need a plan!
TL;DR: Arguing with the Workers’ Compensation Board (WCB) isn’t about emotional confrontation — it’s about knowing how to challenge decisions professionally and strategically. This post offers a step-by-step guide for employers to understand the rules, gather documentation, communicate effectively, and navigate appeals. The key takeaway: your best argument is made before the conflict starts by establishing policies, keeping records, and understanding WCB’s expectations.
When and How to Appeal a WCB Claim in Canada
The best time to appeal a WCB claim depends on the situation and nature of the claim. This is because there are different types of appeals and different levels. I think this is why people get anxious when it comes to WCB.
Technically you can appeal a claim:
- When you submit your employers report
- While having a conversation with WCB
- When you receive the WCB decision letter
To address this even further, there is a difference between a formal and informal appeal.
Typically, a formal appeal happens once a decision is made by WCB. You’ve received their decision in writing, and you’re choosing to formally appeal the decision for one reason or another.
To me, appealing a claim over the phone or through the employers report is considered informal, because what you’re trying to do is influence a decision vs. appeal a decision that’s already made.
The other thing to remember is that depending on the province you are dealing with, they have different timelines for appealing claims.
If you’re not sure what the timeline is in your province, you can call them directly and they’ll tell you.
They can literally be anywhere from 30 days to one year from the date a decision is made.
How Does WCB make a Claim Decision?
There are three elements WCB uses when making a decision. As an employer, you only have control over one of them.
The three elements are:
- Evidence
- Medical
- WCB policy
WCB will review these 3 elements and then determine whether benefits should be approved or denied.
Evidence in a WCB Claim
This is the information that you gather. It tells the story of what happened and then provides proof that what you’re saying is accurate. If you’ve ever heard a picture is worth a thousand words, then think of this as a thousand words to paint a picture.
I want to create a movie in the case managers mind of what happened. The better evidence you can collect, the better decision you’ll get from WCB.
Medical
For a claim to exist there must be an injury that happened at work. No injury = No claim.
You as an employer can’t control this. What a doctor says is based on their professional opinion.
The WCB uses the medical information to establish a workplace incident occurred and that the symptoms seem to be related to the worker’s job in some way. If there is a question about the relationship between a worker’s symptoms and what they said happened at work, the claim could be denied. If accepted, this could be the opening you need to appeal WCB’s decision.
Medical is also used to determine the restrictions a worker has. This helps a company in offering modified duties because they are told what a worker can or cannot do. The employer can then see what they have available to accommodate their work restrictions.
Workers Compensation Board Policy
Each provincial government set out laws to help govern the workers compensation board (WCB) in their province. The WCB then takes these laws, interprets them, and created WCB policies to help decide how they will deal with all aspects of workers comp.
This is why companies often struggle — not because of bad intent, but because of policy and process misalignment between OH&S systems and WCB expectations.
Each province has their WCB policies listed on the workers comp website. To find it simply google: “WCB [province name] policy”
You as a company cant re-write the policy. If we were playing a game, think of policies as the rules of the game. The better you know the rules, the better you can play the game.
The nice part is, you don’t have to memorize the rules. You just have to know where to find them and how to INTERPRET them.
One area that often gets discussed when appealing a WCB claim is the interpretation of the WCB policy.
Although you can’t change what’s written in a policy, you can have a differing opinion about what the policy means. This can often lead to very interesting discussions with WCB.
Now that you know the three elements this is how WCB actually makes it’s decision.
You submit evidence to WCB that tells your side of the story. This includes the employers report of injury.
WCB looks at the story and the medical information on file.
They then look at the policy and decide whether the information meets the workers comp policy or not.
If it does, benefits are awarded. If it doesn’t then they’ll be denied.
Now that you know how policies are made, let’s explore how to have your argument heard.
How to Submit a Strong WCB Appeal: Step by Step
There are different ways you can influence a WCB decision. The areas we will discuss here are: employers report, over the phone, and in writing. Each one has it’s role, but it’s important to understand these roles and be strategic with how you use them.
This is because, using this incorrectly can hurt your chances of a successful WCB appeal.
Employer’s Report
An employers report of injury is a way for you to register a claim with WCB by notifying them a worker reported symptoms they feel are work related. In the majority of cases, this is a straight forward process.
However, there are times where you will question whether these symptoms are work related or not for a variety of reasons. It may be completely true that a worker is experiencing symptoms, but there has to be an employment hazard that contributed to the injury in order to make it work related.
Symptoms you have evidence happened outside of work should be explained to WCB. On most employer’s reports there is a section that asks if you disagree with the acceptance of the claim. Here is where you can state your case. If the space isn’t enough, you can always attach a letter with more information.
The only thing I would caution you on, is be careful and strategic with what you say here. The reason being, if you submit all your evidence and the entire story, WCB could still make a decision against you. In this case, your argument and evidence would be considered a part of the original decision and make it harder to appeal.
In our WCB training for employers, we discuss what’s the best way to fill out an employers report and notify issues you have with the acceptance of the claim.

Over the Phone
There will be times where WCB has made a decision and they’re calling you to explain the decision before sending you the letter. At this point, it’s normally a done deal. Rarely have I seen WCB overturn a decision because of an argument on the phone.
In fact, the last thing you want to do is argue with them over the phone. I will admit, I have fallen to temptation a time or two and had my colorful conversations with WCB, but I can also tell you it didn’t help me.
Here’s an example that I want to share to help make my point. If you watch sports or have kids in sports and you’ve watched them compete, at some point you’re going to see a referee make “a bad call.”
Inevitably, a player or coach will argue with the referee about the call and that they made a mistake. I have never seen a referee from the argument say: “You know what? My bad. You’re right. I messed up. No penalty.”
NEVER HAPPENS!
If anything you get another penalty.
What does this have to do with WCB? When you’re on the phone with the case manager and it seems like you’re going to get a decision you don’t want before you get angry get curious.
Find out how they came to this decision. What evidence did they give you, what medical do they have, and how did they interpret the policy.
What you’re doing is asking questions that will provide you with the blue print to appeal the claim later on. In some cases, you may realize you don’t have an issue to appeal even if you disagree with the outcome.
You don’t have to agree with WCB, but you must understand their decision. This is something most employers miss.
Writing Your WCB Appeal Letter
In the majority of cases, when it comes to appealing a WCB claim, you’re going to be doing it in the form of a letter.
The process will start when you get the WCB decision letter. Hopefully, if they’ve done it right (which isn’t always the case) they will explain the evidence, medical, and policy they reviewed. They will outline what influenced their decision and why they decided this way.
From there you can write your appeal letter and submit to the decision maker.
If you’re worried about writing a decision letter our WCB training will solve this for you. We offer students an easy to follow template that shows you exactly how to present your argument. We then show you HOW to use the template as well as help you write your first letter to WCB.
The 3 Levels of WCB Appeals and How They Work
There are usually three levels of appeals in Canada when it comes to workers compensation claims. This is important to understand and remember because many of you think that once WCB makes a decision that’s it. When in reality, it’s just the beginning.
The three levels of appeals are typically:
- Customer service
- Internal Review Department
- Tribunal
You will have to go through each level before advancing to the next. This is typically done when your appeal is denied at a given level, it then gets sent to the next.
E.G.
A case manager disagrees with your appeal to have your workers claim denied. They then send it to the internal review body which agrees with the case manager. The internal review body sends it to the tribunal. In almost all cases the tribunal’s decision is final.
How to Understand and Respond to a WCB Claim Decision
It’s important to understand a WCB decision in order to understand what a positive outcome looks like. Most people think that a positive outcome means you get exactly what you wanted. While this is true, there are situations where you didn’t get what you want, but you can draw positives from the situation.
Unfortunately, the price of education is usually paid in the claims you lose.
When you appeal a claim properly, you force WCB to give you specific answers. These answers help you figure out why you lost your appeal and what you can do next time to prevent such a thing from happening again.
The first step when you get a decision letter is to understand why WCB made this decision. If you’re unsure, pick up the phone and ask the decision maker. It’s their job to explain their rationale for coming up with that decision. We spoke about how to do this earlier in this article.
LISTEN to what’s being said. If it was an issue with medical or policy, then your options may be more limited than if it came down to evidence.
If it did come down to evidence try to figure out:
- Is evidence missing?
- Can I get it?
- If I can’t, what are my other options?
Sometimes the only option is to live with the decision, but manage the claim properly to minimize the impact it’ll have on your worker, your company, and your WCB premiums.
Appealing WCB claims can be intimidating, but it can also be a rewarding experience. The more you do them and get used to them, the easier they’ll be.
