Try hard to find an upholsterer who has done these before or who at least cares enough to study how they should be done so that he or she gets it right. A lot of upholsterers will just say "yeah, yeah" to your questions and concerns and then do it the way they do any other chair.
There are many good photos of original Papa Bear chairs online where the proportions of the tufting can be worked out. Read the DA thread linked before for more information and be sure to watch the video linked in it.
It will be more work for you to do it this way but you can save money over shipping it to a specialty upholsterer, and a skilled upholsterer who enjoys a challenge and who appreciates fine furniture can do a good job of it even if he/she has never done one before.

Your upholsterer can order from Maharam once she sets up an account (easy enough to do). Their site gives the following as a contact in Canada:
Toronto
60 Adelaide Street East
Toronto, ON M5C 3E4
416.368.7600
416.368.5200 Fax
I get fabric from them without stepping foot into the nearest showroom and I imagine it's no different for your upholsterer in Canada. Get some samples first (no charge for them) so that you're sure of the color.

I guess this isn't news
but I am simply amazed by how hideous upholstery can make a stunning chair...um, hideous? I can't wait to see the chair post make-over

Hideous upholstery
On modern pieces...

Hey Are you consider to...
Hey
Are you consider to sell the chair? I will give you a good price

Not Wegner
I will be the dissenting voice. There is another Danish company called "Svend Skipper" that makes a chair very much like the Papa Bear. A subtle difference is that the Skipper has a straight cut-out on the side of the chair and the Wegner has a slight wavy curve.
The Skipper is not a shabby chair at all. Very comfortable.

I'm always amazed how people...
I'm always amazed how people with incorrect information can be so publicly confident in their statements.
All it takes is a simple 10 second "svend skipper" google search to see that the OP's chair is not a svend skipper. (Hint, if you only have 3 seconds instead of 10, just compare the paws).

Do not change the webbing
Leaving as much original as possible retains more of the value. Some staining is inconsequential. I would only replace the webbing if it was not structurally stable.
Hope you have an expert upholsterer, that is not an easy chair to redo correctly.
