Hidalgo's goal came off a corner kick from Dax McCarty in the 22nd minute. Four minutes later, Zizzo scored with a nice finish at the right post after being set up by McCarty and Mike Grella.
The USA will have two more days of camp, including an intrasquad scrimmage on Friday. Rongen will pick his 20-player roster for January's qualifying tournament in Panama at the end of this camp, and the selected players will have a week off for the holidays before returning to Bradenton on Dec. 30 for an eight-day camp.
The USA was without its four European-based players. Canada used four European-based players. A fifth, Hertha Berlin's Kennedy Owusu-Ansah, was injured.
