Information about Sunnybrook’s new daily vaccine standby list

Once a vial of COVID-19 vaccine is opened, it must be used up. Sometimes at the end of the day, there are a few doses left in an open vial.

To make sure not one dose goes to waste, Sunnybrook is starting a daily standby list for the eligible public. The list is for people who are currently eligible for a vaccine at Sunnybrook’s vaccine clinic. It is for FIRST DOSE ONLY. And you must be able to be at Sunnybrook's Bayview Campus at 7 p.m. if invited. 

Applying for the standby list does not mean you will get a vaccine. In fact, the chance of you getting a vaccine from the standby list is very small. Most days we have less than 10 leftover doses. Some days we have no leftover doses.

How does it work?

Step 1: Check that you are currently eligible for a vaccine at Sunnybrook’s vaccine clinic.

Step 2: Each day between 10:30 a.m. and 12:30 p.m., a form will appear on this webpage. Sign up using your name, email and other required information.

It’s not about being the first person to sign up during this timeframe. Whether you sign up at 10:32 a.m. or at 12:28 p.m., it doesn’t matter.

Step 3: At 12:30 p.m. the list will close. Our team will randomly select 10 people.

Step 4: The 10 randomly selected people will be contacted by email at 4 p.m. and given more instructions about when and where to come on site and standby. (Instructions will be provided in an email)

Step 5: At 7 p.m., the 10 invited people will come standby outside the clinic. Each will be given a number randomly, not in order of arrival. 

Our clinic team will count how many remaining doses they have. If there is one extra dose, one person’s number will be drawn and they will be given a vaccine. If there are two extra doses, two numbers will be drawn, and two people will be given a vaccine.

And so on.

If there is only one leftover dose, only one person will get a vaccine. If there are two leftover doses, only two people will get the vaccine. The other people will not get a vaccine.

The list is new each day. You must fill in the form on each day that you’d like to be considered for a standby dose.

A long list of really important things to know about the standby list:

We realize this standby system will not be convenient or doable for everyone. It is not a way for vaccines to reach a large number of people. It is a way to ensure no dose ever goes to waste.

Appointment bookings via our booking tool and call centre remain open, and other outreach in the community continues with our partners.

This is not a way of “jumping the line” because you must already be eligible for a vaccine. Our vaccine clinic staff will ask you how you are eligible, according to the criteria listed on our website ( If you are not eligible, you will not be vaccinated. Help us help the community by only signing up to this list if you are eligible. We want this to work.

We’ve heard people say “clinics throw out tons of doses”. We can assure you that’s simply not the case. We only have a handful of doses leftover if people do not show up for their booked appointments. Up until now, we have had a standby list for Sunnybrook staff.

Signing up to the list or getting the email to come standby on site is not a guarantee you will get a dose.

Don’t sign up if you’ve already had a first dose. Please. It will slow down our vaccine clinic team and make this process more difficult for everyone.

If randomly selected, you will have to be at Sunnybrook's Bayview Campus at 7 p.m that night. You cannot move it to a different night. Please be careful on your way here and get here safely. Whether you are the first person or the tenth to get here, it does not matter, as long as you arrive by 7 p.m. At 7 p.m., each of the invited standby people onsite will be given a number randomly, not in order of arrival. 

You might have to wait outside for up to 30 minutes so please dress accordingly. After waiting, you might not get a vaccine.

Every day is a new day and a new list, and you must enter your name on the list again if you are available and interested in standing by that day. You can sign up every day if you want. But each day only sign up once.

Please do not come to the hospital unless you get the email that tells you to come and standby. People without standby invitations will be asked to leave.

Remember the chance of getting a vaccine through the standby list is really very small. Applying for the standby list is your choice. Filling in the form does not guarantee you a dose, and being invited to standby on site does not guarantee a dose.
