Hi, my case was very similar to your. Landing for 27th Mar in Vancouver was cancelled. WP was expiring 5-Aug 2020.So what do people do?
I did the same - sent web form on 8-May saying Wp is expiring and requested for telephonic interview. Received generic reply on 12-May saying to just wait.
Received PR confirmation email on 25-May -- about 23 days later.
[One positive news for me before was - MSP care card now can remain active even during implied status due to Covid. This was not so last year. Thanks]
