The Reds have brought in Dwayne De Rosario, Michael Bradley and Jermain Defoe ahead of the 2014 MLS season and former Newcastle United, Sunderland and Birmingham City defender Caldwell is confident they will bring plenty of leadership and direction to the BMO Field.
"It changes things a great deal," Caldwell told MLSsoccer.com.
"I think it is very exciting for us to have more experience. Obviously the quality of the players the club has signed is something that is pleasing to me and everyone else in the organization.
"It is very exciting times. Now we have to do the hard work to prepare for the first game on the 15th of March."
He added: "We are going to gain by the quality of the new guys, first and foremost. Michael will bring such quality in midfield. He is a superb football player. Jermaine has shown his quality at such a high level and De Rosario has that quality that he can change a game in a second.
"First is the quality they bring, but second is their experience, as they have played at such high levels for many different clubs. That's going to be a big difference for us and it will be a big help to a lot of the younger lads."
