Canada has made just one of the allowed six changes to its Gold Cup roster, calling in Orlando City striker Cyle Larin and sending Raheem Edwards back to Toronto FC.
Larin has scored eight goals in 17 matches for Orlando in MLS this season and joins a Canadian side that netted five in its three group matches.
The 22-year-old has five goals for his country in 20 appearances.
Canada finished second in Group A behind Costa Rica and will face the runner-up from Group C at the University of Phoenix Stadium in Glendale, Arizona, on Thursday.
Larin missed most of June after being arrested on a DUI charge, sitting out three games for Orlando before being cleared to return to action by MLS' Substance Abuse and Behavioral Health Program.
