Give this link a look - there's a pdf for the rules that CBSA follow with respect to importation of firearms...
http://www.cbsa-asfc.gc.ca/publications/dm-md/d19/d19-13-2-eng.html
Here's a couple highlights - interesting what they did and didn't do...
IDENTIFYING AND CLASSIFYING FIREARMS
2. When identifying and classifying non-restricted,
restricted, or prohibited firearms under tariff
item 9898.00.00, customs officers are
encouraged to use
the Firearms Reference Table (FRT). The FRT is an
automated application on CD-ROM that provides
descriptions and visual representations of a variety of
firearms.
3.
When a firearm cannot be identified or classified using
the FRT, such as home-made firearms or extensively
modified firearms, customs officers should consult with the
Regional Firearms Liaison officer or the Regional Firearms
Coordinator before detaining it.
Interesting, as the FRT disks clearly indicate it as being a non-restricted rifle with the appropriate number - wonder why it was detained???
This sniglet refers to parts...
20. The frame and receiver of a firearm are considered
firearms in their own right. As a result, the same permit
requirements apply to importing a frame or receiver as they
apply to importing firearms.
21. All components or parts
designed exclusively for use in
the manufacture of or assembly into an
automatic firearm
are
considered to be prohibited goods for the purpose of
tariff item 9898.00.00. The components and parts may be
imported, but only under certain conditions (e.g., with a
prohibited weapons licence).
22.
Customs officers must first ensure that the components
or parts in question are designed exclusively for use in the
manufacture of, or assembly into, an automatic firearm. In
some instances,
the parts may be used on a firearm other
than an automatic firearm, and may be released if all other
requirements are met. Customs officers should make use of
all available expertise to make this decision. The Regional
Firearms Liaison Officer may be able to advise whether the
person or business is entitled to import such items.
the transportation activity.
Wow - the parts have to be EXCLUSIVELY for use in FA firearms... If they can be used in other firearms, it's ok to import them. That sort of kills their argument that the parts make the gun prohibited, not the receiver... Ooops - not looking good for CBSA.
Both CBSA and RCMP have nothing to stand on... In their own testimony some years ago, RCMP expert stated that "true" semi-auto firearms would only have selector positions that read "safe" and "fire"... Are they going to recant this testimony now to say that it's not the receiver, but the internal parts??? Boy they stepped into it deep....
Anyways... Back to my letter writing... Dear Uncle Stevie....
