How hard is it to right a wrongful conviction in Canada?

You would expect that advances in forensics and genetic technology would lead to fewer and fewer wrongful convictions. The truth is that we have no idea how many people are in prison for crimes they didn't commit—we only know that we keep finding them. 

How do wrongful convictions happen in the age of DNA evidence? How hard are they to overturn? And what about all the wrongful convictions that aren't murders? Do we ever try to grapple with those?
