Section 52 of the Constitution Act, 1982 establishes the supremacy of the Constitution over all other laws in Canada:
Primacy of Constitution of Canada
52. (1) The Constitution of Canada is the supreme law of Canada, and any law that is inconsistent with the provisions of the Constitution is, to the extent of the inconsistency, of no force or effect.
Any laws that are found in violation of any part of the Constitution, including the Charter, will be of no force or effect.
Any person with legal standing may make an application to the court declare any provincial or federal law unconstitutional and of no force or effect.
Any challenge to federal legislation requires that notice be given to the Attorney General of Canada.
Arguments challenging the constitutionality of a statute should be heard only at the end of all the evidence.
It has been suggested that Courts should not entertain constitutional issues if it is not necessary to resolve the case.
Where the defence challenges the constitutionality of a provision in the Criminal Code, notice must be given to the Attorney General of Canada. Where the provision is within provincial legislation, Attorney General of the province must be given notice.
There is a presumption of constitutionality for all legislation. When there are "two plausible characterizationagrees of a law, we should normally choose that which supports the law's constitutional validity".
Notice of Constitutional Question
The provincial Judicature Act and/or the civil procedure rules may set out he te requirements of notice for a constitutional question.
Generally, notice must be given to both the Attorney General of Canada and the Attorney General of the province before the issue can be heard.
Evidence in Challenging Legislation
It is accepted that to challenge legislation there should be both "adjudicative facts" and "legislative facts".

Division of Powers
Legislation concerning criminal law must have three prerequisites:
- a valid criminal purpose,
- prohibition, and

Overlap and Incidental Effect
Legislation that overlaps with concerns of other levels of government is acceptable.
Section 7: Life, Liberty and Security of Person
Section 7 of the Charter protects an individual's autonomy and personal legal rights from actions of the government in Canada.
Under the heading of "Legal Rights", the section states:
7. Everyone has the right to life, liberty and security of the person and the right not to be deprived thereof except in accordance with the principles of fundamental justice.
There are three distinct types of protection within the section:
- the right to life,
- the right to liberty, and
- the right to security of the person.
An applicant must establish that at least one of the three rights have been infringed upon as a result of the proceedings against him.
Denial of these rights only result in a breach if they breach "fundamental justice". A remedy can only be achieved if the breach cannot be saved under s. 1 of the Charter.(see Section 1, section below)
The prohibition on possession of marijuana does not engage the "life interest" where consumption could prevent people from being ill.
- Hitzig v Canada, 2003 CanLII 30796 (ON CA), (2003), 177 CCC (3d) 449 (Ont. C.A.)
The right to liberty protects an individual's freedom to act without physical restraint (i.e., imprisonment would be inconsistent with liberty unless it is consistent with fundamental justice). The court described it as "[touching] the core of what it means to be an autonomous human being blessed with dignity and independence in matters that can be characterized as fundamentally or inherently personal."
Any offence that creates a "real possibility of imprisonment" will be sufficient to engage the liberty interest.
The right to security of the person consists of rights to privacy of the body and its health and of the right protecting the "psychological integrity" of an individual. That is, the right protects against significant government-inflicted harm (stress) to the mental state of the individual.
Not every interference will amount to an "adverse impact on security of the person" under s. 7. There must be "serious" "psychological or physical" impact.

Section 12: Cruel and Unusual Punishment
Section 1: Justifiable Limitation of Rights
Remedy for Unconstitutional Provisions
The remedy must be guided by the "principles of respect for the purposes and values of the Charter, and respect for the role of the legislature".
The remedy must be "the measures that will best vindicate the values expressed in the Charter and to provide the form of remedy to those whose rights have been violated that best achieves that objective".
