Former Dryden gunsmith, Bruce Montague is starting to run out of appeals.
The Ontario Court of Appeal upheld his conviction on 26 firearm related charges last week in Toronto.
The three member panel also upheld his 18 month jail term.
The judges ruled that unlike Americans, Canadians do not have a constitutional right to bear arms and possession of firearms is not something that is guaranteed under the Charter of Rights and Freedoms.
Montague has indicated that he will take his case to the Supreme Court of Canada if he has to.
