We had some very good lawyers about 30 years ago that were well schooled on the wildlife act. They were very hard to beat and many cases got thrown out over technical grounds .
Below is an article from New Brunswick about conviction rates. It was 14% for "major" charges. Many were dropped before even getting to trial, but even after that the percentage it not good. So, there must be some good lawyers left out there.

I think it would be great if Nova Scotia appointed a special prosecutor for Wildlife Act charges. They did that recently for Occupational Health and Safety, and it is working well to have a dedicated person.
I do not practice in this area, but I agree with WOT that the regs are hard to interpret. This makes is difficult on both defence counsel and prosecutors, and in some cases more so on prosecutors because they have the burden of proving the law has been broken, which is tough to do when you have trouble giving a clear explanation of the law. "Well judge, the intent of the law in this case is to deter...." is a tough way to start any argument.
