Delivery time for me was one month to Calgary, from date of production, but that was a couple years ago for a 2020. I was lucky and my car sailed through Quality Control (QC) w/o issue. Delivery was by train, then after being unloaded, the final leg of the journey was by transport truck to the dealer. Having said that, from 3000 status to actual delivery can vary GREATLY due to all the possible delays inbetween. I'll let others give you an educated guess on that. Frankly, I wouldn't worry about that, since you'll just drive yourself nuts. Be happy you WILL get a C8, unlike others, and focus on the TPW by having your salesman monitor it, plus ask to be advised when your car hits event Code:
-3800 (vehicle produced, VIN available: get the VIN; it allows you to get insurance or at least a more accurate quote)
-4000 (vehicle available to be shipped)
-4B00 (order bayed; vehicle is waiting on transportation or pulled for QC. Ask your dealer to find out if it HAS been delayed by QC)
-4200 (order shipped)
Your dealer is usually the best source of info. Some contact Shane at the NCM but many are now saying we shouldn't wear him out with enquiries...
Personally and having lived through all this, being anxious/impatient changes nothing, so focusing on what you're going to do when you get the car, is likely a better use of your energy/effort. Read the owner's manual (easily found on-line), research then buy accessories; plan things like PPF/ceramic coating (if desired); talk to your insurer and others to track down the best coverage and rates, etc.
Nice to know there'll soon be another C8 on the road in Alberta (where are you in Alberta?). Good luck and congrats!
