If you are currently on short-term disability (STD) and your benefits are ending soon, you may be wondering: How do I transition to long-term disability (LTD) in Ontario? This is one of the most stressful points in a disability claim—because a missed deadline, incomplete medical evidence, or a gap between STD and LTD can leave you without income.
This guide explains how the STD-to-LTD transition typically works under employer group benefit plans, common problems that arise, and what you can do to protect your claim.

Quick Summary: How STD Usually Transitions to LTD
- STD is designed for short, defined periods when you cannot work due to illness or injury.
- LTD is designed for longer periods when you remain disabled after STD ends.
- Most LTD claims have a qualifying period (often tied to the STD period) and may require a new application package, even if you were approved for STD.
- LTD often uses a different disability test over time (for example, “own occupation” early on, then “any occupation” later), depending on the policy wording.
What’s the Difference Between STD and LTD in Ontario?
While STD and LTD both provide income replacement, they are not identical—and approval for one does not guarantee approval for the other.
STD (Short-Term Disability)
- Typically covers weeks to months (varies by policy).
- Often focuses on whether you can perform your own job (your regular duties).
- May involve frequent check-ins and updated medical notes.
LTD (Long-Term Disability)
- Designed for longer-term disability when you remain unable to work after STD ends.
- May require a more detailed application, more medical evidence, and stricter scrutiny.
- Policy wording may change the test for disability after a set period (for example, from “own occupation” to “any occupation”).

When Should You Start Preparing for LTD While Still on STD?
Ideally, you begin preparing well before STD ends—especially if your condition is not improving and you expect to be off work longer-term.
Preparation matters because insurers often deny LTD claims for reasons that could have been addressed earlier, including gaps in treatment, incomplete medical evidence, or inconsistent reporting.
A practical timeline
- 6–8 weeks before STD ends: Confirm your STD end date, ask whether an LTD application is required, and request any forms early.
- 4–6 weeks before STD ends: Ensure your healthcare providers understand the functional limits that prevent you from working (not just the diagnosis).
- 2–4 weeks before STD ends: Submit the LTD package (or confirm it has been submitted) and keep copies of everything.
Do You Need to Submit a New LTD Application?
Often, yes. Even if you were approved for STD, LTD may require a separate application package or additional forms. The exact process depends on:
- whether STD and LTD are administered by the same insurer or different providers, and
- your plan’s specific requirements and deadlines.
Tip: Ask your case manager or benefits administrator (in writing) what is required to transition from STD to LTD and what the submission deadline is.
What Documents Are Usually Part of an LTD Application?
Although forms vary by insurer and plan, many LTD applications include some combination of:
- Employee statement (your account of symptoms, treatment, job duties, and functional limits)
- Attending physician statement (or medical reports from your doctor/specialists)
- Employer statement (job duties, last day worked, earnings, benefits details)
- Additional medical records or test results (as requested)
The most important point: insurers focus heavily on function—what you can and cannot do—and whether that prevents you from performing work as defined by the policy.
Common Problems During the STD-to-LTD Transition
1) A “gap” in benefits (STD ends before LTD starts)
Gaps can happen when paperwork is delayed, medical information is incomplete, or the insurer takes longer than expected to adjudicate the LTD claim. If you see a gap coming, address it immediately—early action is often the difference between a smooth transition and a denial.
Government EI Sickness Benefits During a Gap
If there is a gap between STD ending and LTD approval, some individuals explore Employment Insurance (EI) sickness benefits. Eligibility and timing depend on your circumstances, and you generally cannot receive EI sickness benefits and private disability benefits for the same period.
2) LTD denial after STD approval
It is possible to be approved for STD but denied for LTD. This can happen when the LTD definition of disability is applied more strictly, when insurers demand more evidence, or when they interpret medical information differently.
3) “Insufficient medical evidence”
This is one of the most common denial reasons. A short doctor’s note may not be enough for LTD. Insurers often want detailed clinical notes, specialist input, treatment plans, and evidence of restrictions/limitations tied to job demands.
4) Missed deadlines or incomplete forms
Late submission or missing information can derail a transition. Keep a checklist and submit documents well before deadlines. Keep copies of everything.
5) Pressure to return to work or attempt a return-to-work plan
Some plans involve gradual return-to-work efforts. These can be appropriate in some cases, but they can also create confusion about whether you remain disabled under the policy. If a return-to-work attempt fails, documentation is critical.
How to Strengthen Your LTD Claim While You’re Still on STD
- Stay consistent: Ensure your forms, medical records, and reported limitations align.
- Focus on function: Document work-impacting limits (concentration, stamina, lifting, standing, sitting tolerance, attendance reliability, etc.).
- Follow treatment recommendations: Insurers often scrutinize gaps in treatment.
- Keep a paper trail: Save benefit letters, emails, forms, and copies of submissions.
- Request clarity in writing: Ask what evidence is needed and what deadlines apply.
What If Your LTD Claim Is Denied After STD Ends?
An LTD denial is not necessarily the end of the road. Your options depend on your policy, the denial reasons, and timing. Common next steps include:
- Requesting the insurer’s reasons and evidence relied on (in writing)
- Gathering stronger medical documentation addressing the insurer’s stated concerns
- Considering an internal appeal if it is required or strategically appropriate
- Considering legal action where appropriate (keep limitation periods in mind)
If your LTD is denied—or you are worried it will be—speak with a lawyer promptly so you do not miss critical deadlines.
Legal claims in Ontario are generally subject to limitation periods under the Limitations Act, 2002. Missing a limitation period can affect your ability to pursue a claim.
Employment Issues During STD and the LTD Transition
Disability claims can overlap with employment law and human rights issues. For example, some employees face termination or pressure at work while they are on disability leave.
Disability Is a Protected Ground Under the Ontario Human Rights Code
In Ontario, disability is a protected ground under the Ontario Human Rights Code. Employers have a legal duty to accommodate disability to the point of undue hardship.
If you are facing termination, pressure to return to work prematurely, or a refusal to accommodate medical restrictions during the STD-to-LTD transition, the issue may extend beyond an insurance dispute and raise human rights concerns.

FAQs: Short-Term Disability to Long-Term Disability in Ontario
Does STD automatically convert to LTD?
Not always. Some plans may “transition” administratively, but many still require a separate LTD package or additional medical evidence. The process depends on your specific group benefits plan.
Can I apply for LTD while I’m still receiving STD?
Often, yes—and it is usually wise to begin early if it appears you will remain unable to work when STD ends.
Why would an insurer approve STD but deny LTD?
LTD claims are often scrutinised more closely. Insurers may apply different policy wording, demand more evidence, or argue your medical information does not meet the LTD disability definition.
What if there’s a gap between STD ending and LTD starting?
Gaps can happen due to delays or disputes. Act quickly, document everything, and get advice if your claim is at risk.
