In what is an interesting news story spotted by Thumpy's 3-D House of Airsoft, whatever the decision of the Supreme Court of Canada will affect ownership of airguns and even airsoft guns. Right now, Canadian airsoft players have to tread a fine line in importing and owning airsoft guns as airsoft guns can be classified as unregulated as long as they have a muzzle velocity between 366 to 500fps on .20g BBs according to the Royal Canadian Mounted Police (RCMP).
Anything below the minimum which will make them prohibited and classified as a Replica or above the maximum which will classify them as Firearms and thus, covered by the Firearms Act.
This is best explained in this chart made by Airsplat. Though it says in the chart that the maximum is 407fps, which is a narrower definition than what is stated at the RCMP website.
Following the link provided by Thumpy, the Ottawa Citizen reports that arguments will be heard by the Supreme Court, in case they agree with the decision of the Ontario Court of Appeal, will make owners of pellet guns to criminal charges and prison sentences if found guilty. The story is already dated, posted on the 21st of February, but so far, we have not heard of news if the Supreme Court already heard arguments on this issue.
The present way that owners of pellet guns are prosecuted only if they the pellet guns are used in intimidation or to cause bodily harm.
