Ah, to clarify, Canada's upper house is basically a house of lords equivalent that we expect to be full of puffed up nobodies that get paid a too generous stipend to sit there and keep their mouths shut. Canada has one elected congress body (the one we all talk about) and then this vestigial senate which is generally expected to sit there and silently approve everything that passes through it.

It does technically have power, but it's like the King's power to veto UK legislation - he can do it precisely once and then he'll be stripped of the power.
