394 Impaired Driving and Other Criminal Code Driving Oences
I. Introduction
Blood may be seized in a number of dierent ways for evidentiary purposes. Blood
cannot be drawn as a screening tool. It may be seized by demand as an alternative
to seizing breath in drinking and operation cases. It may be seized by demand in
drugged operation cases. Warrants may be obtained requiring blood to be drawn from
an accused. Samples of the accused’s blood may also be seized from hospitals where
blood has been drawn for medical purposes. Where hospitals have drawn blood and
tested it for medical purposes, the police may seize the blood and medical records via
warrant to obtain results of the accused’s blood alcohol concentration (BAC) or blood
drug concentration (BDC). In addition, the police can demand samples of oral fluid
or urine for evidentiary purposes.
In this chapter, we briefly explain why blood is better than oral fluid or urine for
evidentiary use. We then set out the demands that may be made to seize oral fluid,
urine, and blood. Chapter 17, The Arrest and Evidentiary Demands, addresses
the statutory preconditions to make reasonable-grounds demands, so we will not
readdress that topic here. We will discuss established case law dealing with when
blood can be drawn as an alternative to breath samples. Also covered are the other
methods of seizing blood, including blood warrants and warrants to seize medical
records. Finally, we will address the competing rights, duties, and obligations at
play when the police are present in hospitals to investigate Criminal Code1 opera-
tion oences.

II. Why Blood Is Preferable to Oral Fluid or Urine as a
Source of Forensic Information
Although evidence about alcohol and drug consumption can be obtained through oral
fluid and urine, blood is a better source of information. The per se drug and alcohol
oences all relate to blood alcohol or blood drug concentrations. Urine or oral fluid
does not provide direct evidence about BDC. The concentration of alcohol or a drug
in urine or oral fluid may not correlate to a particular BDC or BAC.2
III. Practical Challenges in Obtaining Blood
Although blood is a better source of information, it is more dicult for police to
obtain. Historically, blood has been seized only in cases where the driver has been
injured in a motor vehicle accident. It has been virtually unused in routine drinking
and operation or drugged operation cases. The reason is practical. Breath, oral fluid,
or urine can be seized by a police ocer with minimal intrusion and without the
need for medical attention. The seizure of blood must be done by medically trained
personnel, who will draw blood only in medically safe circumstances. Policeo-
cers don’t have the training to draw blood. Even if such training were provided,
ocers would be engaging in behaviour that is directly contrary to the interests of
the accused: investigating the accused for a criminal oence. It may be unreasonable
to expect individuals to permit an ocer, who is not working in the accused’s best
interests, to draw blood.
The practical ramifications of seizing blood mean that a non-police actor must be
involved in the process—historically, a medical doctor or medical technician. There-
fore, the police must secure the cooperation of a doctor or technician who likely has
a number of other responsibilities and duties to address, not least of which is a duty
of confidentiality toward the patient. Section 320.37(2) of the Criminal Code per-
mits medical personnel to draw blood in response to a demand from the police and
exempts them from liability when doing so. Part VIII.1 of the Criminal Code does not
contain a provision compelling medical personnel to cooperate, nor does it make non-
cooperation a criminal oence. Section 320.37(1) of the Criminal Code specifies that
medical practitioners and medical technicians shall not be found guilty of any oence
for refusing to draw blood if they have a reasonable excuse for doing so. The authors
are unaware of any case where a hospital sta member has been charged for refusing
to draw blood.
