As a broker we have a wsib list set up for all of our carriers that automatically renews or not depending on paid premiums. I understand the issue from the original posters comment. On the actual date they are due to renew our data base all expire on the same day a logistic nightmare to update them all on the same day as an expired wsib blocks our ability to assign a carrier to a shipment . I tried originallly to renew a few days early and I couldn't, not sure it they have changed that. A work around is to stagger the renewal dates for a couple of days so we can get a chance to update in our system.
