CVAS Registration Guide

You register for CVAS by completing four forms. This can now be done from within the CVAS app.

To help you to get up and running on CVAS as quickly as possible, we can pre-register you. Please send an email to the Help Desk at with your first and last name, a username and password, and your email address and smart phone number. You will receive a return email that will outline the next steps to complete your registration, which are also below. The email will also include the Terms and Conditions for the use of CVAS, which would have been accepted on your behalf.

If you do not wish to be pre-registered, go to Step 1 in the various registration guides below.

If you ask to be pre-registered, you will also receive an email as outlined in Step 6 below. You will then need to follow the remaining steps in the Registration Guide and then download and install the CVAS app on your mobile phone. If you prefer to change your password to one that will not be known to CVAS staff, once you have completed the CVAS registration, you can use the "Change Password" option on the log in screen. To locate this option swipe down on the log in screen until the voice over reads "Forgot password button".

If you prefer to complete the registration forms, you will do so by using the commands applicable to your screen reader, which are noted in the step by step instructions below to complete the forms.

Step 1 - Login

To log in for first time, open the CVAS application and you will hear “Username edit box CVAS”. CVAS will already be in the first input field at the top of the log in screen. Enter your user name.

Then, locate the next field and you will hear “Editing Password Edit box”. Enter your password.

Locate the Login button and select it to log into the application.

After you have logged in for the first time, you will remain logged in unless you choose to log out of the application.

Below is a description of the other important items contained on the Welcome screen:

  1. Navigate the app until you hear “Welcome, your user name and My Contacts”.
  2. Continue navigating and you will hear “Favourites”, which will already have included the contacts from you mobile phone.

Remember, CVAS is dependent on the quality of the Internet service to you and the agent. This may have a direct impact on the service and can cause interruptions. Should that happen, please call back. If you do not reach the same agent, you can ask to be transferred to the agent you were interacting with.
