Argo kick returner Trent Guy picked up special teams honours for his role in the win.
B.C. Lions linebacker Adam Bighill took the defensive player award, while Calgary Stampeder slotback Jabari Arthur was named top Canadian.
Kackert ran for a season-high 155 yards in Saturday's win over Edmonton, including touchdown rushes of 49 and five yards, as the Argos won their fourth road game in a row.
Guy returned four kicks for 131 yards as the Argos came back from a 21-point deficit and clinched a playoff berth.
The Lions also clinched a playoff spot with a dominating 53-17 win over Winnipeg on Friday. Not only did Bighill menace the Bombers' offence, he scored the first touchdown of the game when he recovered a fumble and took it 30 yards for a touchdown.
Bighill also recorded 10 tackles, one sack and two forced fumbles.
Arthur, a Montreal native, caught six receptions for a game-high 103 yards and hauled in two touchdowns in the Stampeders' 35-11 win over the Tiger-Cats on Saturday that kept Calgary alone in first place in the Western Division.
