Dobirstein, A federal crime is a federal crime. To be in illegal possesion of a firearm is not a provincial crime. Federal prosecutors are used in situations where the province would prefer to not get invoved. If the province wishes, they can reserve these cases for federal prosecutors.A fish and wildlife officer is looking for offences that are commited in the commision of an offence pertaining to the wildlife act. Yes, a wildlife officer can arrest you for impaired etc, but how many officers carry a breathalizer? If they suspect you are impaired the responibility is on them to prove you are. You should read the wildlife act and criminal code. Better to be informed on these matters and defend your rights than to assume that the people who administer the law are all powerfull and knowledgeable. Most people are not willing to question a police officer or other person of "authority" and therefore end up in a pile of mess, when the mess could have been avoided by asking questions and chalenging the officers knowledge of the law.
Just a few things to consider...

They can have my guns when they pry them from my cold dead fingers.
