I don't think he's even worth a flyer. He's had a great ST, but even if he makes the team (and he's doing all he can to force JP and Tosca to keep him) he isn't going to get regular at bats. He'd end up in a platoon in left with Catalanotto and Reed Johnson and might be able to spell Rios in right a little. Even if you factor DH into the mix (where Catalanotto might get some at bats), you've got 3 positions (LF, RF, DH) for 5 players (Rios, Little Cat, Johnson, Hillebrand (or Hinske, whoever isn't playing 1B) and Gross).
I think from the Jays perspective it makes more sense to let him get at bats at AAA. Alternatively, name him the starting LF and hope the ST streak continues, then once he cools down send him down. That said, until he's named the starter I wouldn't take him -- too many other OFs out there.
