After the horrible collapse by the bullpen last night, there was understandably a lot of anguish about how bad the Jays bullpen looks. The meltdown in the 9th hides the fact that the bullpen did a good job in the previous two innings. I do think the team suffers from not having a reliable arm to close a game, but as a collective, they seem to have reasonably well if you look at shutdowns vs meltdowns (data from Fangraphs).
A reliever earns a shutdown by collecting +.06
5 WPA and a meltdown by collecting a -.06 5 WPA (such as Perez last night). See http://www.fangraphs.com/library/index.php/pitching/sd-md/ for more information about these stats.

And here's the shutdowns and meltdowns for the individual Jays relievers*
FWIW, after an entire season, an average reliever will have about 1.6:1 SD:MD and a replacement reliever about 1:1.
