If you’re too sick or injured to work, long term disability (LTD) insurance is supposed to be your financial safety net. But misconceptions about how LTD works can stop people from applying, push them back to work too soon, or make them give up after a denial.

Below, we unpack five common myths about LTD insurance—and what you actually need to know to protect yourself.

Myth 1: “If I’m really sick, my claim will be approved without any problems.”

Many people assume that if their illness or injury is serious, their LTD claim will naturally be approved. Unfortunately, that’s not how insurance companies work.

Insurers are businesses. They earn money by collecting premiums and protecting their bottom line—not by paying out every claim. A large percentage of LTD claims are initially denied, often for reasons like “insufficient medical evidence” or “you don’t meet the definition of disability,” even when someone is clearly unable to work.

That doesn’t mean your case is weak or that you did something wrong. It usually means:

• Your medical documentation isn’t detailed enough yet.
• The insurer is downplaying the impact of your symptoms.
• An internal “consulting doctor” has given an opinion that contradicts your treating doctors.
  
  

What you can do: Treat a denial as part of the process, not the end of the road. With proper medical support and experienced legal help, many denied claims are ultimately resolved in claimants’ favour.

Myth 2: “LTD only covers certain diagnoses, not my condition.”

Another widespread myth is that only specific diagnoses qualify for LTD benefits—things like cancer, heart disease, or catastrophic injuries. If your condition is less visible or harder to “prove,” you might assume you don’t qualify.

In reality, LTD policies in Canada focus on the severity of your symptoms and how they affect your ability to do your job, not just the label on your diagnosis. Any condition can potentially qualify if it prevents you from performing the essential duties of your occupation. That includes:

• Mental health conditions such as depression, anxiety, bipolar disorder, or PTSD.
• Chronic pain and fatigue conditions, including fibromyalgia.
• Neurological and autoimmune conditions.
• Environmental sensitivities and other less-understood illnesses.
  
  

Insurance companies often resist claims involving invisible or complex conditions. They may say there’s not enough “objective” proof, even when your doctor strongly supports your leave. That’s where detailed medical records and, in many cases, legal advocacy become crucial.

What you can do: Don’t disqualify yourself. If your symptoms make it impossible to do your job reliably and safely, you should explore an LTD claim, regardless of the diagnosis name.

Myth 3: “If my doctor says I’m disabled, my insurance company has to agree.”

Your doctor’s support is very important—but it is not automatically decisive for your insurance company.

Insurers routinely:

• Have their own doctors review your file (sometimes without ever examining you).
• Rely on internal “guidelines” for how long certain conditions should last.
• Downplay or reject treating physicians’ opinions, especially for mental health and chronic pain.
  
  

You may see denial reasons like:

• “Insufficient medical information.”
• “You do not meet the definition of disability.”
• “Our medical consultant believes you can return to work.”
  
  

That can feel like a personal attack on your credibility or your doctor’s competence, but it’s really part of how insurers try to limit payouts.

What you can do:

• Ask your doctor for detailed narrative reports, not just short form letters.
• Ensure your records describe specific limitations at work (concentration, lifting, attendance, stamina), not just diagnoses.
• If a denial is based on an insurance company doctor’s opinion, get legal advice right away rather than arguing directly with the insurer.

Myth 4: “If I miss a deadline or make a mistake, there’s nothing I can do.”

LTD policies are full of timelines—when you must apply, appeal, or start legal action. Denial letters often emphasize 30–, 60–, or 90–day appeal windows, which can make you feel like one error ends your chances.

Deadlines are serious. For example:

• Many policies require you to apply within a set period after your elimination period.
• There may be a contractual limitation clause to sue after denial.
• Provincial limitation laws also set outer time limits to start a lawsuit.
  
  

Missing a deadline can give the insurer a strong argument against paying benefits, but it doesn’t always mean your claim is hopeless. Sometimes there are legal tools and arguments that can keep your claim alive, depending on the policy wording and timing.

What you can do:

• Apply and seek advice as early as possible—don’t wait until you feel “sick enough.”
• If you think you’ve missed a deadline, contact a disability lawyer quickly. There may still be options, but delay makes things worse.

Myth 5: “Appealing directly to the insurance company is my best next step.”

Most denial letters invite you to send in an “appeal” for internal review. It sounds simple and cooperative. Many people believe the appeal process is their only pathway, or that they must exhaust appeals before seeking legal help.

In practice, internal appeals:

• Are often reviewed by the same company, under the same policies, with the same incentives.
• Rarely overturn initial denials without significant new evidence.
• Can eat up valuable time while limitation periods for legal action continue to run in the background.
  
  

Insurance companies know that people who handle appeals alone are at a strategic disadvantage. They understand the fine print and deadlines; most claimants do not.

What you can do:

• Before filing an appeal on your own, speak to an LTD lawyer about whether that’s truly in your best interest.
• In many cases, moving towards a legal claim and mediation—rather than cycling through multiple internal appeals—gives you a better chance of a fair settlement.
  
  

Long term disability insurance can be confusing and intimidating by design. Understanding how it really works—and where the myths lead people astray—can help you make informed decisions, protect your benefits, and know when it’s time to get legal support on your side.
