They do not ship the PR card outside.
Yes he will need PRTD to visit Canada again (which takes time, but becomes an easy and the only option if you know that PR card application was approved.
I am overseas on a work assignment and one of my colleagues from Canada will be travelling to relieve me in a few weeks. I was going to ask them to bring my mail which I was hoping would include my PR card. If not, then yes, I will need to obtain a PRTD to return on a commercial flight to Canada (although one can apparently still cross the land border into Canada in a private vehicle, although not exactly a convenient option).
 
Update: Local MP office contacted IRCC and IRCC told them the same thing that agents tell me i.e. application is under review. MP office told me they also speak with call center but a different call center than general public.

No expected timeline provided.

Silence since then. My employer and professional body are asking for valid PR card.
A similar story for me - my local MP office contacted IRCC who confirmed that my application has been received and 'is in progress'. I applied on June 3rd.
