Sir, maybe I can provide an answer to the questions you're looking at.
These firearms were imported into Canada, the CZ was first imported in 2005, the Swiss Arms was first imported in 2001. The firearms when imported were believed to be non-restricted and the determination of classification was made as such. Information came to light that identified them as being something other than what they were purported to be, namely that the CZ was a variant of the Czech VZ-58, which is a prohibited firearm, and that the Swiss Arms Classic Green, which was purported to be a variant of the SG-540, which is a non-restricted firearm, was in fact a variant of the Swiss SG-550, which is a prohibited firearm.
Consequently these firearms were determined to be correctly prohibited firearms. The previous legislation, Bill C-42 , deemed them to be non-restricted and restricted based on barrel length, but that did not change the determination made by the Canadian firearms program in terms of their classification in accordance with the Criminal Code.
