Regulatory and Provincial Offences
Regulatory offences (or "public welfare" offences) come in three categories:
- mens rea offences: offences that require "some positive state of mind such as intent, knowledge, or recklessness, must be proved by the prosecution either as an inference from the nature of the act committed, or by additional evidence".
- "strict liability" offences: offence with no mens rea where the act creates a prima facie case that requires the accused to show "all reasonable care".
- "absolute liability" offences: offences where it is "not open to the accused to exculpate himself by showing that he was free of fault."
Only true criminal matters can be "mens rea offences".
The elements of provincial or regulatory offences, defences and all evidential standards must be proven on a balance of probabilities 
In strict liability offences the Crown does not need to prove intent. The defences of due diligence and mistake of fact are valid defences.
In absolute liability offences the Crown does not need to prove intent.The defence of due diligence is not available.
All offences outside of the Criminal Code that are not defined as indictable are deemed to be summary offences.
Similarly, the provisions within the Code that concern indictable offences will relate to indictable offences found in other Acts and provisions in the Code concerning summary offences will apply to summary offences in other Acts unless otherwise stated.
Applicability of the Criminal Code
All federal summary and indictable offences are subject to the procedures of the Criminal Code except where otherwise provided. As stated in s. 34(2) of the Interpretation Act:
Criminal Code to apply
(2) All the provisions of the Criminal Code relating to indictable offences apply to indictable offences created by an enactment, and all the provisions of that Code relating to summary conviction offences apply to all other offences created by an enactment, except to the extent that the enactment otherwise provides.
R.S., c. I-23, s. 27.
The general approach is that unless the Act creating the offence explicitly excludes the application of the Criminal Code, then it will have application. s

Del Mastro, 2016 ONSC 2071 (CanLII) at paras 148 and 149 (“law is well settled that, ...the provisions of the Criminal Code will apply to offences created under another Act of Parliament, unless Parliament has clearly expressed an intention to the contrary…The general rule is that the Criminal Code is only ousted, if the statute in issue contains a ‘complete code.’ However, the fact that a statute may be silent, or that the statute has some provision touching upon the same subject matter as a provision in the Criminal Code, is not sufficient to manifest an intention on the part of Parliament to exclude the Criminal Code”)

Inspections and Investigations
An inspection is the same as a search within the meaning of s. 8 of the Charter, however, given that it is non-criminal, no warrant is needed so long as it is authorized by a statute.
An inspection will turn into a full investigation once "the predominant purpose" of an officer's inquiry "is the determination of penal liability". It is this moment where the "adversarial relationship crystallizes". Once an investigation has begun, the inspecting agent must then comply with all procedural requirements for search and seizure.

Determining Category of Offence
There is a presumption that regulatory offences are "strict liability".
The judge should consider factors to determine the type of offence:
- overall regulatory pattern and context of the section,
- the subject matter or type of conduct regulated;
- the purpose of the act;
- the community interest in its regulation
- the nature of the penalty; and
- the precision of the language used
Offences that use language suggestive of a mens rea, such as “wilfully”, “with intent”, “knowingly”, or “intentionally”, will likely be "mens rea offences".
The greater the penalty to more likely it will be a "mens rea offence".
Offences that contain the words "permit" or "cause" are typically ones of strict liability.
Even where the penalty is "severe", the offence may still be strict liability where the public safety is not compromised by the conduct and the wording of the offence does not indicate guilt as require proof.

Strict Liability Offences
An Ontario seatbelt law under provincial road Act was not found to be strict liability.
e.g. R v Kanda, 2008 ONCA 22 (CanLII)
Absolute Liability Offences
Absolute liability Offences that are punishable by a period of imprisonment violate s. 7 of the Charter and are not permissible.
