If (and that is the operative word)... if Edmonton can work out a growth-oriented cargo relationship with a burgeoning West Coast Port -- namely Prince Rupert/Port Edward -- and was able to combine their joint efforts with an inland distribution Hub which Edmonton is geographically well set up to be, then I could see Edmonton becoming a Distribution Centre that services all of western Canada and a sizable chunk of the western and mid-western U.S.
Several things are required to achieve that:
1. the political will to "get after it"... foremost relying on better cooperation between Federal, Provincial, and Municipal governments
2. alignment of aims with Prince Rupert
3. rail transit improvement through two mountain ranges -- those being the Coastal Range and the Rockies.
4. cooperative agreements between CN and CP
5. connective agreements between key cities -- Calgary, Winnipeg, Denver, Minneapolis, KC, and Chicago are among the most important, but smaller cities could assist too.
6. a sh**load of investment capital
Edmonton's advantages in line with achieving that goal include:
1. historical precedence as "Gateway to the North"
2. an extremely large (area wise) airport with lots of land for development of a transportation hub
3. the previously noted Geographical advantage for near straight-line connectivity to western and mid-western market centres
4. a competitive advantage over more constrained Ports that have nearly maxed out their growth potential
5. a willingness to support new transportation modes -- e.g. high-speed rail (no matter what form that may take)
6. a reverse load capability in (particularly) hydrogen and hydrogen industrial by-products that would be of interest to Eastern Markets... that plus Agricultural products (collected from the same hinterland that would be supply recipients) and Agricultural By-products.
7. a huge post-secondary infrastructure -- NAIT, UofA, MacEwan U, Concordia U, Athabasca U, NorQuest -- lots of bodies to develop a work base and extend employment in key fields.
8. low-cost labor market, excellent ElHi schools, relatively inexpensive housing, and a gloriously beautiful City that, too, has lots of room for growth.
The development of this Hub/Inland Port/Radial Network would also have extreme benefit for the City, the Province, and Canada. And I know there are some on this Skyrise Cities Site who can imagine and ideate lots of spin-off for this, covering or adding to points that I have overlooked.
