I hadn't paid much attention to the Winnipeg Canad Inns Stadium previously, but watching this YouTube video (below) it is quite an interesting, simply built stadium with most of the seats between the goal-lines. I am referring to the current Winnipeg Stadium not the new stadium.
What if just the top tier of the Canad Stadium design was copied and built new with the bottom tier as a sunken design (many new stadiums, including the new Winnipeg Stadium are sunken designs to make access easier). Having the bottom section sunken would cut down on access ramp requirements. The Canad Inns stadium appears to have a large proportion of folding seats. It also has a large partial roof. Canad Inns Stadium is a stadium design has been tested in harsh Canadian winters for over 50 years (so I think that we can say that the design will be structurally sound). Copying a proven design will cut down on architectural/engineering costs, which could quite easily be several million dollars. New retro baseball stadiums have become very popular so why not for football also?
The Canad Inn Stadium was built in 1953 for $483,000 dollars -

I realize this would be more in today's dollars but even if a similar design was built new then the cost might only be in the $60 - $70 million dollar vicinity for 29,000 seats ($2,000 - $2,500 per seat). Has anyone been in this facility? It looks like a fun stadium to watch a sports or concert event in.
It nothing else, it shows a proven design that would have good sight-lines. It is also expandable for a Grey Cup and has hosted a few Grey Cups.
