yes, my mother is the sole applicant, dad had passed away long back. I had sent the webform back on the same day as PPR (June 4th) , June 10th i had got acknowledgment from IRCC agent saying they have forwarded the information regarding ready for visa letter to the responsible office and then June 19th i got the P1.Hi hims0912.
Congratulations! So happy for you.
I'm in the same situation as you. Except my mom received his passport request letter on May 06. My mom is here but my dad is not in Canada. My mom is the primary applicant. Like you, I sent the webform informing them that my mom is in Canada and my dad is back home. We received the acknowledgement, and have been waiting ever since for the P1 email. I wonder why it's taking them so long. Is it because my dad is back home. I sent them a webform last week and they just replied with everything is ok and we need to wait.
Was your mother the sole applicant?
I had read on the forums and YT videos back from 2022 here that in past for virtual landing request people tried to email IRCC at below address to request and used to get P1 response so i did try this and had sent email on June 9th but i really doubt if it worked or helped my case in any way as i had not received any acknowledgment or anything for this, this was me just being impatient unnecessarily actually so had tried it

[/td]i think best approach is to wait out as in your case one parent is inside Canada and other is not and since you have informed IRCC about this already so i guess just wait for IRCC instructions. This process is known to take super long and very lucky we all got picked last year
