I received same email as text message,I don’t have application number
This could be a system glitch at VFS, if you had the application number/UCI, you could have linked your application online to see the actual application status.
Either your application is processed really fast, which is little difficult to believe as they send a correspondence letter first validating your biometrics for next 10 years (check your inbox also spam folder) and then they give the decision OR it is just a system issue at VFS.
Keep looking for a Visitor Acknowledgment Email in your inbox/spam, you would have the application number and UCI in there. You could create a new GC key on cic.gc.ca until then and then link your application online to see the IRCC status. VFS is just a mediator and does not show the IRCC updates about your file.
Steps;
Create a new GC Key account. On the link
https://www.canada.ca/en/services/immigration-citizenship.html, click "Sign in or create an account to apply online" on right and go down a little to "continue to GC Key" and click it. Now click "Sign Up" on the right and create a new profile. Remember the answers to the security questions that you'd be setting at this time.
Once that's done, login again and click "Add (link) your application to your account " on the User's account page.
Select category as "temporary residence" and sub-category as TRV. Under "Application details" select last option. Enter UCI, no hyphens and no space. Enter Family Name as last name on passport (upper/lower case matters). Next, select passport form drop down.
Enter all other fields as filled in application form. And click "search my application". If all fields are correct it will give you the application and you can proceed with linking it. If not, it give you 4 more attempts in 24 hours and then it would ask you to try again after 24 hours.
