What to do if you have COVID-19 symptoms

If an individual has symptoms that are not compatible with COVID-19 symptom, they should stay home until symptoms are improving for at least 24 hours (or 48 hours if gastrointestinal symptoms), to limit the spread of other illnesses that the individual may have (e.g., common cold virus, Influenza, other viral respiratory or gastrointestinal illness) and to monitor for the development of additional symptoms.

Do I need to have a negative follow-up test before I return to work?

  • You do not require a negative COVID-19 test result to return to work. You may return to work when your period of self-isolation ends, providing you do not have a fever and your symptoms have been improving for 24 hours (or 48 hours if you have gastrointestinal symptoms). In addition, you will need to pass the COVID-19 screening questionnaire to enter your workplace.

What does a negative COVID-19 test mean?

  • A negative COVID-19 test means you probably were not infected at the time your sample was collected.
  • It does not mean that you will not be exposed to, test positive for, or become sick with COVID-19 in the future.
  • If you have had contact with a confirmed case of COVID-19, you should continue isolating for the remainder of the time required as a contact of a confirmed case.  If your symptoms persist or worsen, contact your doctor. For those who had previously been instructed by public health to isolate, you should remain in isolation for the remainder of the required -isolation period.
  • If you have not had contact with a confirmed case of COVID-19, tested negative but still have symptoms: follow these guidelines for individuals with symptoms
  • If you have not had contact with a confirmed case of COVID-19, tested negative and have no symptoms: you can resume your normal activities, including returning to work.
  • If your test comes back negative, but you begin to develop COVID-19 symptoms, even if they're mild, you should isolate immediately. Read more about what to do if you have COVID-19 symptoms.

What does a positive test mean?

  • A positive COVID-19 test means you are most likely infected now and could infect others.
  • You should self-isolate and follow these instructions.
  • Public health or the provincial work force will reach out to you to provide further instructions by phone or text message if you work in a high risk setting.


Can the test tell me if I had COVID-19 in the past?

  • No, the test only determines if you have COVID-19 at the time the test is conducted.
  • Testing someone’s blood to see if they have antibodies for COVID-19 can tell if a person previously had COVID-19, however in Ontario, this test is only done in very limited clinical situations.

I am a health care worker

I am not a health care worker

I was tested due to an upcoming surgery/medical procedure (I do not have symptoms and was not exposed to a person who tested positive for COVID-19)

  • You are not required to self-isolate while waiting for your test results.
  • Please contact the physician responsible for your upcoming surgery/medical procedure for more comprehensive guidance.

Testing after travelling abroad

Travellers entering Canada, regardless of citizenship, must follow testing and quarantine requirements. There are different requirements for vaccinated and unvaccinated travellers. Information about returning to Canada from abroad from the Government of Canada  


  • Fully immunized person - A person is defined as fully immunized 14 or more days after receiving their second dose of a two-dose COVID-19 vaccine series of their first dose of a one-dose COVID-19 vaccine series that is listed for emergency use by World Health Organization or approved by Health Canada.
  • Previously positive person - A person is defined as previously positive if they were a confirmed case of COVID-19 where their initial positive result was 90 days ago or less AND they have been cleared from their initial infection.
  • Exposure - in general, this includes household, prolonged (>15 minutes cumulative) or close (<2 meters) contact, as well as other potentially high-risk contacts.

Testing for people who are not close contacts, do not have symptoms, or need tests for travel

Participating pharmacies and labs for those without COVID-19 symptoms.  

Individuals must follow public health measures when going for a test, including wearing a mask, practising physical distancing and cleaning hands frequently. If you are feeling sick on the day of your appointment, please stay home and re-schedule your test.

The Ontario Government does not cover the cost of COVID-19 testing for travel. These tests are only available at private laboratories for a fee. Please ensure you book the test required by the location you are travelling to.

Individuals who are seeking clearance for travel must get tested at a participating pharmacy or lab.

Point of care (rapid) testing

There are two kinds of point of care tests (POCT): molecular and antigen tests.

Antigen POCT
Antigen POCT tests are used for screening purposes only and should not be used for diagnosis of COVID-19 infection in people who have COVID-19 symptoms or who have had close contact with a positive COVID-19 case.

Rapid antigen testing may be used to confirm if a symptomatic individual has COVID-19, with no requirement for a confirmatory PCR or rapid molecular test. Please refer to eligibility criteria above for individuals who should seek confirmatory PCR testing after receiving a positive rapid antigen test.

For all other individuals, if you receive a positive Rapid Antigen test result, consider yourself as positive for COVID-19, immediately isolate and notify your contacts.

A negative result on a single test cannot rule out a COVID-19 infection by itself. If you have symptoms, take a second test 24 to 48 hours later, if available. If your second test taken within 48 hours of your first negative result is also negative, this most likely means you do not have COVID-19.

Molecular POCT
Molecular testing is for both diagnostic and screening purposes. A confirmatory test is not required. All POCT final positives from molecular tests must be reported to the local public health unit.

Learn more about point of care testing

Individuals who are not vaccinated and are required to complete regular screening for work purposes are not eligible for testing at Assessment Centres.  Speak with your employer to access Rapid Antigen testing.

Beginning February 9 until at least July 31, free Rapid Antigen Tests (RATs) will be available at 2,300 participating grocery stores and pharmacies in Ontario. 

Who can access rapid antigen testing:

  • People with symptoms of COVID-19
  • People without symptoms of COVID-19 for screening purposes

Anyone who receives a positive result through their rapid test should consider themselves as positive for COVID-19, immediately isolate and notify contacts. Only those who individuals who meet the eligibility criteria outlined above should seek confirmatory PCR testing at a COVID-19 Testing & Assessment Centre or participating pharmacy. These persons should also notify their employer for further direction.
