I can perhaps provide some insight for those of you with tracking numbers, but severely delayed deliveries...
My rifle was shown as "In transit" from Calgary on January 26th. It has not had any updates, and right off the bat of receiving tracking info (Jan. 30) it was listed as "delayed".
After some talking with Canada Post, opening a service ticket, having it's priority upgraded, and being forwarded to a senior supervisor... I was informed the package was flagged as "improperly shipped" by their inspectors, and is being held or returned to the sender, which of those is happening was not made clear to me.
What WAS made clear to me is that I have no further recourse as the receiver, and I must contact the shipper (TI) to inform them. It will then be up to TI to contact Canada Post and sort it all out. I've just sent my email to TI, so no response yet.
Hopefully that helps some of you with your next course of action.
