2020 STUDENT REGISTRATION IS NOW OPEN & MUST be COMPLETED by Wednesday, March 11th, at midnight.

Students who have not completed on-line registration by this closing date will not be allowed to participate in the science fair for these reasons.


Click here if you already received an email with your Team Number and Registration Number.

Registration is on a first-come, first-serve basis – you must complete all the registration steps on time to be in the fair.

3 steps to registering:

  1. Complete the form below – an email will be sent to you after you submit it with your account details.

    Initial account creation may take up to two days to process. If you have not received a response by this time, please phone the TVSEF at 519-691-6892 and leave a detailed message with your name and phone number. In your message, say your phone number slowly and then repeat it.

  2. Complete the rest of the registration before the registration deadline.
    You can only use this system after your information has been entered by the registrar.
    If you already have an account, click here to go to the Online Registration System.
    This step MUST be completed before the registration deadline noted above. 
  3. Return the signed permission form one week before the fair.

It must be submitted via Canada Post, fax, or emailed as a PDF file. The address, phone number and fax number are given on the form.

Please note that image files (such as .jpg, .jpeg, etc.) will not be accepted because the photos of the form taken via a phone are often illegible.


The deadline for all entries is midnight on March 11, 2020. The online registration must be completed by this date.


Late applications will not be accepted. It takes several days to assign judges and print all the forms.


Prior to the registration deadline, if you decide to withdraw, please inform the Registrar as soon as possible so that your space can be reassigned.


If your project involves the participation of humans, including yourself or your immediate family, you must read the Youth Science Canada Policy on Human Participation

If your project involves the use of animals, you must read the Youth Science Canada Policy on the Use of Animals.


Make sure you visit the Rules page before you start your project. Entries which do not comply with the rules of the Thames Valley Science & Engineering Fair may be refused. The decision to deny entry rests with the Fair Committee and such decisions shall be final.
