Here's a look at convictions that have led to consecutive murder sentences in Canada

Edward Downey was sentenced Tuesday to life in prison without the possibility of parole for 50 years for the 2016 killing of a Calgary mother and her young daughter.

He joins a list of multiple murderers who have been sentenced to serve more than 25 years before they are eligible for parole.

In 2011, the Conservative federal government amended the Criminal Code in the case of multiple murders, allowing for parole eligibility to be stacked, or served consecutively, for each conviction.

Here is a look at some other cases where the law has been applied.
