Here is a link to an outfit I have used with good results, providing you give them very clear instructions. They travel Australia, North America, and Europe about four times a year.
Go to this
site and look for this link:
Elite Collection - Super 120s Fine Wool with Cashmere in Colored Pinstripe 1.2 cm wide ( Price : $ 225.00 )
There is a photo there of a swatch that matches your description. These guys don't update the site very often, so the fabric shown may or may not be available, so I suggest that you write to them to check.
They haven't announced the dates and cities for their March trip through the US and Canada, but there is a form there you can complete to get on their mailing list. They don't send mail more than a few times a year, so I don't get spam from them myself.
Winnipeg is a fair distance from the cities I remember being on their list, but one of the prices you pay for living in city in the middle of the North American continent is that you are pretty far from other cities. The closest city I remember from their last tour was Minneapolis.
