Once you have registered your finalists for the Canada-Wide Science Fair (CWSF), how they are notified depends on whether your region used the YSC Portal for its regional fair. This article explains both scenarios and covers how to resend the invitation if a finalist didn't receive it.
In this case, you enter each finalist's name, email address, grade, and gender into the YSC Portal manually, along with their basic project information. You then assign one or two finalists to each project.
Once a finalist is entered, the portal automatically sends them a welcome email with their portal login details. This is sent to every finalist you register — there is no distinction between new and returning finalists in the current version of the portal.
In this case, your finalists already have a YSC Portal account from their regional fair registration. To register them for CWSF, you promote their project (and its attached students) to the CWSF in the portal.
No email is sent automatically when you do this. You'll need to let your finalists know directly that they've been selected, and ask them to log back into their portal account at portal.youthscience.ca. Once they do, they'll see the CWSF registration menu in the sidebar.
If a finalist didn't receive their invitation email — for example, because an incorrect email address was entered initially — you can resend it manually.

To resend the CWSF invitation:
The invitation will be sent to the email address currently on file for that finalist. Make sure the correct email address is saved before sending.
