All ages that are stated on this wiki are confirmed. In fact, pretty much anything stated as fact on this wiki can be trusted to be canon.

The transition from peaceful to terrorist for the White fang didn't happen overnight. The leadership change was 5 years ago, but I think it evolved over time even after. She says that they started vandalizing, robbing, and sabotaging, and that people were fearing them. I think the change in human view would not be instant, so it took a while.

The stuff got more and more violent over time, until it reached the point of cold-blooded murder. Which is when she left. My guess would be that the Black Trailer happened anywhere from 2 years to 4 months before the start of the series.
