I saw in october spreadsheet they all had an app received date wc probably means they all sent thru courier or registered mail. I sent mine regular mail as friends also just did regular mail usually takes 4 business days within Canada and went fine, until i stumbled upon this thread and thought i should have just did courier as everyone else did. Just hoping it gets received by the PO box in Nova scotia before it reaches 90 days as i remembered the online calculator form is only valid within 90 days.
