I don't know of any. Through American television and American newspapers we've all experienced a sentencing report in which someone received three life sentences, and hearing them talk about the expressive integrity of the justice system. In Canada, the courts concluded many years ago, after a lot of consideration, that you can't--in the abstract, in theory, or in reality--have a sentence consecutive to a life sentence. When someone dies, his life is over. This has been Canadian law for a long time. Anything else is just notional.
