Some disagreement over how much the Tories actually managed to accomplish last time around. Gov. whip Jay Hill says:
Our Conservative Government introduced a total of 70 bills and, even in this minority parliament, 34 of those bills, or half, received Royal Assent.
Michael Geist, on the other hand, puts the number a bit lower, and has the links to back him up:
Only 27 of the 64 Government bills introduced during the current session have received royal assent, leaving 37 bills in need of a restart.
Either way, back in the 38th parliament the Libs were batting .560. Furthermore, one of the bills passed was Bill C-38 - the Civil Marriage Act. Compare that to the bucket of chicken-feed this session represents.
