We most certainly live in interesting times. I never thought I would see licensed firearms owners defending the minister tasked with implementing Canada's latest gun ban, but here we are. Have a look around, plenty of these folks are defending the minister & posting his tweet refuting Ed Burlew's legal opinion that the OIC impacts 10ga and 12ga shotguns with removable choke tubes.
Let's recap.
Ed Burlew is a lawyer & wrote a detailed opinion for the CSSA. The minister is not a lawyer & his tweet is hardly something you could use to defend yourself in court with. And as others have said, the judge will look at the OIC, which is now law, and make a ruling which will set a legal precedent.
What we know is that 10ga & 12ga shotguns with their screw in choke tubes removed, exceed the 20mm OIC as written. Furthermore, screwing in a choke tube to make the bore diameter less than 20mm, is like attaching a flash hider and claiming it increases barrel length. Both are illegal.
The Technical Spec for measuring a shotgun, requires the choke tube to be removed.

By now, I'm hoping you are starting to see the light as to where the confusion comes in...
Here's an example:
A Winchester SX3 shotgun with it's choke tube out exceeds 20mm. (0.836" = 21.23mm)

Where though, I have yet to see, is it cited that measuring the removable choke are is "The forensic Standard"
