I sent a webform mid-April because my work permit and WP-ext letter had expired and Service Ontario refused to renew my health card. I sent the webform explaining this and requesting a renewed WP-ext letter to be able to get access to healthcare. Two weeks later... WP approved.
Not sure if this would work for you but it may be worth giving it a try.
Applied CWP along with SOWP on August 9th
Received correspondence letter for both on April 29th
SOWP was approved on May 1st and received hard copy yesterday (May 5th)
Where as my CWP, there is no update even after a week. Any one in same situation..?
