The Auty Cup was completed on Saturday with a Twenty20 victory apiece for USA and Canada in Florida.
Having already won the two-day and one-day games, the tourists looked set to make a clean sweep when they won the first T20 fixture by 36 runs.
USA finally restored some pride with a comprehensive 46-run win in the second 20-over match at Lauderhill.
Canada skipper Rizwan Cheema (54 off 29 balls) and Hiral Patel (54 off 55 balls) got the visitors off to a flying start in the opening encounter with a first-wicket stand of 86 inside 11 overs.
Japen Patel (4-26) led the USA fightback and a total of 148-9 was disappointing after such a strong platform.
Timothy Surujbally (27 off 10 balls) got the run-chase off to a fine start but when he retired hurt the innings went into freefall. Jeremy Gordon (2-23), Raza-ur-Rehman (2-21) Damodar Daesrath (2-22) all took two wickets as USA were bowled out for 112.
USA exacted revenge in the day/night match when they posted the highest score of the day - 162-5 after winning the toss.
Timil Patel struck 67 not out off 55 balls while fellow top-order batsmen William Perkins (32 off 21 balls), Nicholas Standford (18 off 22 balls) and Barrington Bartley (26 off 14 balls) offered good support.
Skipper Cheema was Canada's most successful bowler with 2-20.
Canada's pursuit of 163 began in reasonable fashion but once both openers fell on 32 the innings petered out to 116 all out. Bartley completed a fine all-round display with 3-14.
Raza-ur-Rehman's 28 not out was all in vain but the defeat could not put too much of a damper on a successful tour for Canada.
