Short answer: In the first week after a workplace injury in Ontario you should report it to your employer the same day, get assessed by a health professional, make sure the injury is documented, file your worker’s report with the WSIB, and start rehabilitation early. Doing these five things in the right order protects both your recovery and your claim. Here is how that week actually goes, day by day, from a clinic that treats injured workers across Scarborough every day.
Why the first week matters so much
Most of the problems we see with workplace injuries have nothing to do with the injury itself. They come from delays. A worker finishes the shift with a sore back and hopes it will settle. A supervisor says to see how it feels tomorrow. A week goes by, the pain is worse, the paperwork has not started, and now the claim is questioned because nobody reported anything at the time. Meanwhile the injury has stiffened, the worker has started moving differently to protect it, and what should have been a two week problem has become a two month one.
The reverse is also true. Workers who report immediately, get assessed within a day or two and begin treatment in the first week tend to recover faster, return to work sooner and have far fewer complications with their claim. The Workplace Safety and Insurance Board, the WSIB, is designed to support exactly that. The system works best when it is used early.
This guide walks through the first seven days. It is written for workers, but supervisors, HR staff and family members will find it useful too. If you have already passed the first week, do not stop reading; everything here still applies, and starting late is far better than not starting.
Day 1: report the injury and get first care
Tell your employer immediately
Report the injury to your supervisor or manager the same day, even if it seems minor, even if you can finish the shift, and even if you are not sure it is serious. Say what happened, where, when and what hurts. If your workplace has an incident form, complete it; if not, send a short email or text so there is a written record with a time on it. Ask for the names of anyone who saw the injury happen.
Employers in Ontario are required to report a workplace injury to the WSIB within three days when it requires health care or results in lost time or modified work. They cannot discourage you from reporting, and they cannot penalize you for doing so. Workers sometimes delay because they do not want to cause trouble or lose hours. Please do not. A late report is one of the most common reasons a claim is questioned, and an unreported injury that worsens is a far bigger problem for everyone.
Get assessed by a health professional
For a serious injury, go to the emergency department. For everything else, see a doctor, a walk-in clinic, a nurse practitioner or a physiotherapist within the first day or two. In Ontario, physiotherapists are primary care practitioners, so for musculoskeletal injuries such as strains, sprains and back or shoulder injuries you can come directly to a clinic like ours without a referral. The health professional who first sees you completes a report to the WSIB describing the injury, and that report is part of what opens your claim.
Tell the health professional clearly that the injury happened at work, how it happened and which tasks are affected. That information shapes both the treatment and the documentation.
Look after the injury
For a fresh strain or sprain, protect the area, use ice and compression for comfort if there is swelling, avoid the movements that reproduce sharp pain, and keep the rest of your body moving. Do not test the injury repeatedly to see whether it still hurts, and do not push through a full shift of heavy work on day one if the injury involves your back, shoulder or knee.
Day 2: open your claim and start the paperwork
File your worker’s report
You file your own report of the injury with the WSIB, either online or on paper. It asks what happened, your job details, your symptoms and the health care you have received. Claims must be filed within six months of the injury, but filing in the first week keeps everything moving. Keep a copy.
Know the three reports
Three reports usually open a WSIB claim: the employer’s report, your worker’s report and the health professional’s report. Each is filed separately. You do not need to coordinate them; you simply need to make sure yours is done and that you have seen a health professional who will file theirs. Once the WSIB has them, you receive a claim number, usually within days. That number goes on every form and bill afterwards.
Start a simple record
Keep a note on your phone of dates, who you spoke to, what you were told, and how your symptoms change. It takes a minute a day and it can resolve a dispute months later.
Day 3: book your physiotherapy assessment
By the third day most workers know whether the injury is settling on its own or not. If you still have pain that limits your movement or your work, book a physiotherapy assessment. You do not need to wait for your claim number or for approval. A WSIB approved clinic can assess you, start treatment and submit the treatment plan while the claim is being processed, and bill the WSIB directly once it is approved. You pay nothing for approved care.
At Physio Cottage in Scarborough, new workplace injuries are usually seen the same or next day. The assessment covers the injury, your job demands, your current abilities and the goals for return to work. You leave with a treatment plan, a short home program and the paperwork started. If you need a doctor’s assessment or imaging first, we tell you and write to your doctor. See our WSIB injury rehabilitation page for how treatment works.
What to bring
- Your claim number if you have it; if not, the date of injury and your employer’s details.
- Your health card and photo identification.
- Any notes, imaging reports or discharge papers from the doctor or hospital.
- A description of your job: what you lift, how long you stand, whether you drive, climb or work overhead.
- Comfortable clothing that lets the injured area be seen and moved.
Day 4: begin treatment and your home program
Early treatment is not about pushing through pain. It is about settling the injury, restoring safe movement and preventing the stiffness and guarding that make everything slower. In the first week that usually means gentle manual therapy, pain relieving treatment such as electrotherapy or acupuncture where appropriate, and a short home program of two to four exercises that take under ten minutes. You will be told what normal post treatment soreness feels like and what is not normal.
Begin the home program the same day. Workers who do it consistently finish treatment sooner, and it is the part of recovery that happens when nobody is watching.
Talk about work from the first visit
Your physiotherapist needs to understand your job in detail, because the goal of treatment is defined by it. A lifting job, a desk job, a driving job and a nursing job need different recoveries. Early in the first week we also begin thinking about modified duties: what you could safely do now, so that returning to work can start as soon as it is safe rather than after you feel completely better.
Day 5: understand modified work and your abilities
Modified or suitable work means duties that fit your current abilities while you recover. It might be shorter shifts, a lifting limit, a different task or a temporary change of station. Research and our own experience both show that workers who return to modified duties early, within what the injury allows, recover faster and are less likely to develop long term pain than those who stay off until they feel fully healed.
Your employer may ask for a functional abilities form, which your treating health professional completes. It describes what you can do: how much you can lift, how long you can sit, stand or walk, whether you can climb, reach overhead or drive. It does not contain your diagnosis. The form is updated as you improve, and it is what makes a safe, gradual return to work possible. We complete these forms as part of treatment and we are honest in both directions: we do not clear workers for duties they cannot do, and we do not hold them back from duties they can.
If your employer has no suitable modified work, say so to your case manager at the WSIB; return to work specialists can become involved, and your treatment documentation supports that process.
Day 6: check on the claim and your rights
By now you should have a claim number or be close to one. If you have not heard anything, call the WSIB at 1-800-387-0750 to check. Confirm your employer has filed their report and ask whether anything else is needed from you.
Your rights as an injured worker in Ontario
- You choose your treating health professional. Your employer cannot require you to use a particular clinic.
- You cannot be penalized or dismissed for filing a claim.
- Approved treatment is paid by the WSIB; you should not be paying out of pocket for approved care.
- If you lose wages because of the injury, you may be entitled to loss of earnings benefits, decided by your case manager.
- If a decision on your claim goes against you, you can object in writing within the time limit on the decision letter, and the Office of the Worker Adviser helps non unionized workers free of charge.
Your responsibilities
- Report promptly and accurately, and tell the WSIB about changes in your condition or employment.
- Attend treatment and follow the home program.
- Cooperate with reasonable return to work efforts.
- Keep your employer informed about your abilities and your appointments.
Day 7: review and plan the next two weeks
At the end of the first week you should have a clear picture: what the injury is, what treatment looks like, what you can do at work, and when the next review is. A typical plan at this point is two or three treatment visits a week for the next two to four weeks, with the home program daily, and a return to modified duties as soon as your abilities allow. Progress reports go to the WSIB from the clinic so that approval continues as long as treatment is helping.
If after four to six visits you are not improving, a good clinic says so and changes course: a different approach, a referral to a doctor for imaging or a specialist opinion, or a specialized program. Treatment that is not helping is not something you should be continuing, and it is not something we continue.
The injuries we see most in the first week
Scarborough’s workforce is varied, and so are the injuries that arrive at our clinic at Victoria Park and York Mills. These are the most common, and how the first week usually goes for each.
Low back strain from lifting
The single most common workplace injury. Pain after a lift, a twist or a long shift of bending. First week: settle the guarding, restore movement, start gentle core and hip activation, and plan lifting limits for modified duties. Most workers are on modified work within one to three weeks.
Shoulder strain
From overhead work, pulling and repetitive reaching. First week: calm the irritation, restore range in the pain free arc, and avoid overhead loading until the rotator cuff tolerates it. Overhead duties are usually the last to return.
Knee and ankle sprains
From twisting on wet floors, stepping off ladders or uneven ground. First week: rule out fracture, control swelling, restore movement and start balance work early. Jobs on ladders or uneven ground need extra balance training before full return.
Neck and repetitive strain injuries
Desk workers and line workers with neck, forearm and wrist pain from sustained postures and repetition. First week: ease the tension, begin posture and mobility work, and identify the workstation or task change that will stop the problem returning.
Injuries from vehicle use
Drivers and operators with back and neck injuries from vibration, awkward cabs and sudden stops. If a road collision was involved, accident benefits through auto insurance may apply as well as the WSIB; we help work out which. See motor vehicle accident rehabilitation.
Mistakes to avoid in the first week
- Waiting to see if it settles. Report and get assessed now. If it settles, the claim simply closes.
- Not telling the health professional it was a work injury. The documentation needs to say so from the first visit.
- Complete rest. Lying on the couch for a week weakens the tissue and delays recovery. Relative rest, which means avoiding the aggravating activity while staying active, is what the injury needs.
- Pushing through a full shift of heavy work. Modified duties exist for a reason. Use them.
- Paying out of pocket. Approved treatment is billed to the WSIB by the clinic. If a clinic asks you to pay for approved care, ask why.
- Skipping the home program. It is the part of treatment that carries results beyond the clinic.
- Keeping no record. A one minute note each day can save weeks of dispute later.
When to go to a doctor or emergency department first
Physiotherapy is the right starting point for most muscle, joint and soft tissue injuries. Go to a doctor or an emergency department first if you have a possible fracture or a visibly deformed joint, cannot put weight on a leg, have a head injury with confusion, vomiting or worsening headache, have numbness in the groin, weakness in both legs or loss of bladder or bowel control, have chest pain or shortness of breath, or have a deep wound or a burn. Once serious injury is ruled out, rehabilitation can begin, and we can usually see you within a day.
Frequently asked questions
Do I need a doctor before I can start physiotherapy for a work injury?
No. Physiotherapists in Ontario are primary access practitioners and can be the first health professional to assess a workplace injury and complete the report to the WSIB. Many workers see a doctor first, and that is fine too.
What if my employer tells me not to report it?
Report it anyway. Employers are required to report injuries needing health care, and workers cannot be penalized for filing a claim. If you are being discouraged, note the conversation and contact the WSIB directly.
Can I start treatment before my claim is approved?
Yes. A WSIB approved clinic can assess and treat you while the claim is pending and bill the WSIB once it is approved.
How many physiotherapy visits will the WSIB cover?
Treatment is approved in blocks based on the injury and your progress. The clinic sends progress reports, and approval continues as long as treatment is helping. There is no fixed number.
Will my employer see my medical information?
Your employer receives information about your functional abilities, meaning what you can and cannot do at work, not your diagnosis or medical history.
What if the injury happened weeks ago and I did not report it?
Report it now. Claims can be filed within six months of the injury. Explain the delay honestly, see a health professional and keep records from this point on.
Can I have massage therapy or chiropractic care under the WSIB?
Often, yes, when it is part of an approved treatment plan. At Physio Cottage these services are in the same clinic as physiotherapy, so we coordinate the plan and the billing.
I work in Scarborough but live elsewhere. Can I still be treated at Physio Cottage?
Yes. Many of our WSIB patients work near Victoria Park and York Mills and live across the GTA. Evening and Saturday hours make it practical.
A worked example: one week, start to finish
To make this concrete, here is a typical first week drawn from the cases we see, with details changed. A warehouse worker in his forties near the 401 feels a pull in his low back lifting a pallet of stock on a Monday afternoon. He tells his supervisor before the end of the shift and completes the incident form. On Tuesday morning he sees a walk-in clinic doctor, who confirms a lumbar strain, rules out anything serious and completes the health professional’s report. That evening he files his worker’s report online. On Wednesday he calls Physio Cottage and is seen the same evening. The assessment confirms a muscle strain with a lot of guarding, no nerve involvement and a job that involves repeated lifting of up to twenty kilograms. He leaves with gentle treatment done, three exercises recorded on his phone, advice on sitting and sleeping positions and a treatment plan submitted to the WSIB that night.
On Thursday his employer asks for a functional abilities form. We complete it: no lifting above five kilograms, no repeated bending, sitting and standing in alternation, four hour shifts to start. On Friday he returns to modified duties on the scanning station. By the following Wednesday, after three treatment visits and a week of the home program, his pain is halved and his lifting limit is raised to ten kilograms. Three weeks later he is back on full duties with a lifting technique he did not have before and a five minute daily routine he keeps for the next few months. The WSIB received the reports on time, he paid nothing for care, and the whole episode took a month. The same injury, reported a week late and rested on the couch, routinely takes three.
How long common injuries take to recover
Every worker asks. The honest answer depends on the injury, the job and how consistently you attend treatment and do the home program, but these are the ranges we commonly see at the clinic. Your physiotherapist gives you a personal estimate after assessment and updates it as you progress.
- Low back strain: modified duties within one to three weeks, full duties within four to eight. Heavy lifting jobs sit at the longer end.
- Shoulder strain: six to twelve weeks for most strains, longer for significant tendon injuries. Overhead work returns last.
- Ankle and knee sprains: two to six weeks for mild sprains, eight to twelve for moderate ones.
- Neck strain: four to ten weeks, with headaches often the last symptom to settle.
- Repetitive strain of the wrist and elbow: six to twelve weeks, and the outcome depends heavily on changing the task or workstation that caused it.
- Fractures after the cast comes off: six to twelve weeks of rehabilitation to restore movement and strength.
How a WSIB approved clinic supports you
A clinic that treats workplace injuries regularly does more than treatment. It completes and submits the health professional’s report, treatment plans and progress reports on time; it completes functional abilities forms in plain language your employer can act on; it tracks approvals so your care is never interrupted waiting for paperwork; it coordinates physiotherapy, chiropractic care, massage therapy and acupuncture when a plan calls for more than one service; and it communicates honestly with the WSIB about progress, which protects you when treatment is working and when it is not. Ask any clinic you are considering whether they are registered with the WSIB and whether they bill directly. If the answer to either is no, you will be doing the paperwork and fronting the cost yourself.
