It's more than that. I gave one part of the report. The rest of the report speaks to the same problem. If you look at sentences awarded for less than a year, you'll see that the percentage of instances where that occurs has increased significantly over the last decade.
There's an overriding message in that Statistics Canada report, which tells us that there has been erosion in sentence length over the last decade. It's that simple, regardless of how you look at it. There are fewer instances of longer sentences and many more instances of shorter sentences.
