There is a wide range of drug related charges.

Drug prosecutions are often highly intricate and defending drug cases requires specialized knowledge of the Criminal Code of Canada, the Controlled Drugs and Substances Act, the Canadian Charter of Rights and Freedoms and the common law. 

The Crown must proves that the substance found is in fact an illegal drug and they often do so by issuing a certificate. It’s important that you work with an experienced lawyer who can identify any problems with this certificate and what impact those problems have on your charges.

These types of criminal charges require several types of defences used in conjunction with each other. 

Many drug prosecutions are based upon evidence obtained through a search warrant, the use of wiretaps or undercover techniques. These strategies are often subject to Charter scrutiny, and evidence stemming from an infringement of your Charter rights may be discounted from your proceedings.

If you are charged with a trafficking offence, the police may have obtained evidence of your identity through surveillance. In some circumstances, improper identification can result in a withdrawal or an acquittal.

Our lawyers will also seek to find other defences to your drug charge.  It may be that the drugs were found in a car that was borrowed or that other people were in the car or using your car prior to your arrest.  It may also be that other people were in your home or living in your home at the time police found drugs in your home.  It may also be that the police did not follow proper procedures in determining the nature of the drug seized such as continuity of the drug or proper analysis of the drug.  These defences are not exhaustive but are only some of many that Roulston Criminal Defence Firm will assess in reviewing your case with you.

Roulston Criminal Defence will always seek to find a Charter issue to defend your drug charge and to have the evidence excluded at trial.  Often, the police will violate the accused’s Charter rights in obtaining evidence.  The Charter violation may occur while driving a car or even walking down the street.  The police may have violated your Charter rights by entering your home even if they have obtained a Search Warrant.  We will carefully review and analyze the Search Warrant to determine if the Search Warrant was granted in error.  It is imperative that the drug lawyer you hire is experienced and diligent in Charter applications so that your matter may be properly defended and your Constitutional rights protected.  If your Charter rights are not properly evaluated then you may be missing out on a defence of your criminal matter. 


If you are a first time offender charged with possession of a soft drug (such as marihuana), you may be eligible for the Alternative Measures Program (AMP). If AMP is successfully completed, your charges will be withdrawn.

AMP requires consent from the Crown so it is important to have an experienced Criminal Defence Lawyer who can make these options available to you.

The result of being found guilty will vary depending on your criminal history and personal circumstances. Typically, the quantity and type of drugs found in your possession will be a major factor. Our lawyers have successfully dealt with gram, pound, and kilogram level prosecutions for the entire spectrum of narcotics.

Some offences carry a mandatory incarceration period, while others may be resolved with a fine or a period of probation. For example, if you are convicted of trafficking and the incident involved a firearm, there is a minimum sentence of one-year imprisonment.

The legal reality is that if you are found guilty of a criminal drug offence, there is a likelihood that you will face some kind of incarceratory sentence –perhaps even time in a Federal Penitentiary.

A conviction for a drug related charge may, and in most cases does limit your ability to travel. The United States have strict policies and readily refuse to admit those with drug related convictions.
