[6] Mira signed a multi-year contract with the Montreal Alouettes of the Canadian Football League (CFL) in August 1972,[7][8] completing 92 of 168 passes for 1356 yards and 11 touchdowns and eight interceptions in 1973.

With the Birmingham Americans of the new World Football League (WFL) in 1974, he was MVP of their championship game victory,[9] completing 155 of 313 passes for 2,248 yards and 17 touchdowns and 14 interceptions during the season.
