GAME RULE RATIO

Each team may have a maximum of 44 players, including 3 players who shall be identified as quarterbacks and 41 other players, of whom not more than 20 may be international players.

Each team may dress a 44-man active roster consisting of:

3 QBs (no designation)
Maximum of 20 international players (4 of which must be identifed as designated internationals)
Minimum of 21 national players

The only reason I point it out is because I am not sure too many American players know that about the CFL. So American players could end up being cut even though they are better than Canadian players because of the rules.
