They infringe on the right to self-defense, the right to property, the right to keep and bear arms....in general. The current Canadian Firearms Act infringes on the right to be secure from unreasonable search, the right to remain silent, the right to be presumed innocent, and is an intrusion on the right to privacy.....look a little harder.
I've lived in Canada all my life, and I've never felt the need to be strapped when I walk down the street. None of the things you've mentioned above has ever happened to me even though I'm relatively weaponless at all times.
Now I'm not a lawyer by any means, but I'm pretty sure that all of the things that you've mentioned are guaranteed to us anyway...
As for the nugget.....try Anglo-Saxon tradition, the nobles that forced John to sign the Magna Carta in 1215, John Locke, the guys that penned the English Bill of Rights, William Blackstone, Thomas Jefferson, James Madison and the rest of the guys that wrote the US Bill of Rights, and on and on and on.......
I'm not sure where you get the notion that the Magna Carta contained any protections for the rights of the people to bear arms. The only right that the Magna Carta offered to the general public was the right of Habeus Corpus. As you said, the nobles forced John to sign Magna Carta, but not for any reason but to protect their own elite status. Obviously the feudal barons would not have been very comfortable with a well armed serf population...
As to the Second Amendment:
Origin of the right
The concept of a universal militia originated in England.[11][12][13] The requirement that subjects bear arms and serve military duty,[14][15][16][17] dates back to at least the 12th century when King Henry II obligated all freemen to bear arms for public defense (see Assize of Arms). At that time, it was customary for a soldier to purchase, maintain, keep, and bring his own armor and weapon for military service. This was of such importance that Crown officials gave periodic inspections to guarantee a properly armed militia. King Henry III required every subject between the ages of fifteen and fifty (including non-land owning subjects) to own a weapon other than a knife. The reason for such a requirement was that in the absence of a regular army and police force (which was not established until 1829), it was the duty of every man to keep watch and ward at night to capture and confront suspicious persons. Every subject had an obligation to protect the king’s peace and assist in the suppression of riots.[18] This remained relatively unchanged until 1671, when Parliament created a statute that drastically raised the property qualifications needed to possess firearms. In essence, this statute disarmed all but the very wealthy. In 1686, King James II banned without exception the Protestants' ability to possess firearms, even while Protestants constituted over 95% of the English subjects. Not until 1689, with the rise of William of Orange, was this reversed by the English Bill of Rights which declared that "Subjects which are Protestants may have Arms for their defence suitable to their Conditions, and as allowed by Law".
