Commonwealth Stadium? Hope not. Too simple. And Edmonton already has a stadium called that.
I hope our politicians seize the opportunity to name this facility after a prominent Hamiltonian. This stadium will be the Ticat lair (and the home of many, many local sporting events) for decades.
Ralph Sazio Stadium
Like every other new stadium it'll be corporate.
Dofasco Field at Tim Horton's Park or some such.
The RALPH......
Right now the Stadium is Pam am Stadium..
after the games
I vote Harold Ballard Stadium or Civic Stadium
I just hope they don't name it after some politician. . . and Sazio's legacy is tarnished by his association with the blue team down the highway.
How about Mosca Field?
Henley Stadium?
Tiger Cat Stadium !!!!
Juravinski something or other. 
It should be named after a CFL legend.
Ron Lancaster Stadium.
I think we are past the age of naming things after Politicians.
What about a war hero?
The last Canadian VC winner Smokey Smith? Foote after the RHLI.
John MaCrae? (in flandrers Fields)
Dieppe after the Dieppe Raid where most victims were from Hamilton?
How about Juno Beach?
Or dedicated to all Veterans VETERANS STADIUM
It'll be about money, and really there isn't anything wrong with that, as long as the money is sufficient to warrant a name.
Tiger Park thats the name
Onknight Field 
Veteran's Stadium.
I like it.
It will be named after the corporation that forks over the most money
Copps Coliseum, tear down Copps as it is now and build a nice 9000 seater for an OHL team. :thup:
How about just "Lancaster" Stadium.
I wouldnt be surprised if it ended up being named after Bob's IT company.
Honda Civic Stadium at Angelo Mosca Place.
Thank you for your attention and edification. LOL
