You can raise a web form form if you are the one who submitted his application and if he signed a Use of Representative form in your favour. If he didn’t sign a Use of Rep form but you used an email address that you have access to, you can send a web form as if he is the one sending it in his name.
Raising a web form will not affect his application. But you would be lucky to receive a reply from IRCC. June is still too recent in my opinion. I have one for a spouse that is pending since April 5 and it’s not even being reviewed for eligibility.
You may try with a web form, but it doesn’t affect anything in terms of expedited processing. If you are in Canada, you can apply for the visa officer’s GCMS notes under the Access to Information and Privacy Act (ATIP) to know what they are saying and the stage where the application processing is. It takes minimum of 30 days to process an ATIP request.
Good luck with your application!
