This is my observation so far:
First couple of days was all for FedEx, then we had Canada Post, and now Purolator. I think this is what happened (can be wrong, so let me know what you think):
FedEx, Purolator, CanadaPost, etc. dropped the applications all within minutes of each other. So CIC received hundreds of applications from each of these couriers and put them in the same stack (i.e. FedEx applications together, Purolator applications together, etc.). As CIC know all of these are within the 5000 cap, randomly picked up FedEx stack and started processing them, then Canada Post, and from today, Purolator ones....
This makes sense to me as there is no way CIC signed for receiving each application. CIC signed once for all hundreds of application from each carrier, that is why we see for example all applications for first AM delivery for FedEx were received at 9:41.
So in my opinion, you guys should not be worried if your CC has not been charged and you used for example UPS. It is because CIC has not reached to UPS early AM applications yet.
Just my 2 cents, I hope that helps you guys nt to be super worried about this process.
Good Luck to you all.
