Scientific evidence is necessary to establish that a substance is a controlled substance. Mere layperson identification of drugs is not enough.[1]

The usual way of proving the nature of the substance is by a Certificate of Analysis. Under s. 51(1) of the CDSA, the certificate is presumed proof of the nature of the substance.

While a certificate is the most frequent manner of proving the nature of a controlled substance is it not mandatory.[2] Where a certificate is not used the substance can only be proven by the expert testimony of a qualified analysis.[3]

Where several stashes of drugs are found, the court may infer that the drug found in one location matches drugs that were tested and confirmed as being a controlled substance.[4]

Proof of Substance

There is some suggestion that proof of a substance as a controlled substance can in limited situations be possible without a certificate of analysis by means of circumstantial evidence.[5]

It is permissible to prove the nature of a large volume of substance by the drawing of inferences from a random sampling or random testing of the whole.[6]

Where a certificate of analysis has been admitted for the proof of the type of controlled substance that was seized, there is no need to produce the actual drug in court.[1]

Objections to the admissibility of certificates must be made at the time that the certificates are tendered and not after the Crown has closed its case.[2]

– LRCDAS (CanLII), (Jus.)

Note up: 51(1) et (2)

Service of Notice

Notice upon accused's counsel is sufficient notice.[1]

There is some question of whether service by fax of a certificate of analysis is sufficient, particularly where Rules of Court requires service more than fax.[2]

Service in relation to a proceedings on an information will equally apply to a proceedings on a replacement information.[3]

  1. ↑ R c Finlay, 1991 CanLII 1048 (BCCA), 65 CCC (3d) 225, par Toy JA, ("It has been settled law in this Province for several decades that service of a notice of intention to produce a certificate of analysis and the certificate on an accused's counsel rather than on the accused personally satisfies the requirements of s. 9(3) of the Narcotic Control Act")
  2. ↑ R c Phung, 2011 ABQB 427 (CanLII), 50 Alta LR (5th) 329, par Nation J, -- in this case, fax not sufficient
  3. ↑ Finlay, supra ("This Court has also held that a notice and certificate served in the course of proceedings on an information that is subsequently withdrawn at the trial and replaced by a second information charging the same offence is valid service and that the certificate of analysis is admissible")

Timing of Notice

There must be "reasonable notice" of the intention to admits the certificate.[1]

Factors to consider whether notice was reasonable to include: [2]

  • complexity of the case;
  • time between the arrest and trial date;
  • intervention of holidays and non-work days;
  • accused's access to counsel;
  • the content of the certificate and notice;
  • prejudice created by the timing of notice;
  1. ↑ s. 51 of CDSA
  2. ↑ MacFarlane, Fraser, and Proulx "Drug Offences in Canada"

Reasonable Notice to Adduce a Certificate of Analysis

The Defence must get "reasonable notice" of the Certificate of Analysis. Reasonableness depends on the complexity of the case, the amount of time passed, the client's access to counsel, and the degree of prejudice created by the possibly late notice. The Crown must prove that notice was provided with notice of a "true and accurate" copy of the notice.

The Defence can ask for leave to have the Analyst brought into court for examination.

Note up: 52(1) et (2)

Oral notice accompanied by copies of the certificate served upon a receptionist, or other secretarial staff of the law office should generally not suffice.[1] Service of written notice with a copy of the certificate "may be adequate in certain circumstances."[2]

Proof of Substance by Other Means

Proof of marijuana has in rare cases be establish by "circumstantial evidence surrounding the circumstances of seizure of the substance and evidence relating to the appearance of the substance by a person claiming familiarity with the product."[1] The same has been accepted for proof of cocaine.[2]

However, court caution the use of any "short cuts" to proof that do not require a certificate.[3]
