Unlike other elements of Canadian military uniforms, ownership and wearing of CADPAT is subject to section 419 of the Criminal Code of Canada as well as military regulations. Simply put, unless personally authorized in writing, only military members may lawfully be in possession of CADPAT. Currently, only the NB DNR is autorized to wear CADPAT on the job and then only in poacher "observation" missions. CP Gear, Dropzone Tactical and Warrior Gear are authorized to make regulation rank badges and non-military cut clothing and equipment in CADPAT. Also regulation CADPAT is cut up before disposal, if you see CADPAT on someone who is not military or is ex military, it is stolen. Some member is without his kit or has sold his kit illegally.
419(a) says "wears a uniform".
Not a piece of a uniform. Given that, I'd find it highly unlikely someone would get convicted for wearing a boonie cap as one piece alone does not constitute a uniform. The act is written to keep people from trying to pass themselves off as an official.
Now if the act stated something like "wears any uniform item", then ya, it would be different. Lacking insignia, etc, and it isn't so much a uniform anymore.
The section also does not say it is illegal to possess such items, only illegal to wear a uniform of the CF when not entitled to by the CF.
Plus summary conviction. Not arrestable unless found in the act of actually wearing said uniform.
"419. Every one who without lawful authority, the proof of which lies on him,
(a) wears a uniform of the Canadian Forces or any other naval, army or air force or a uniform that is so similar to the uniform of any of those forces that it is likely to be mistaken therefor,
Is guilty of an offence punishable on summary conviction."
Anyways, off topic. Can carry this on elsewhere....
