Tonii Roulston has defined her career defending some of the highest profile and difficult sexual assault cases. She understands that just the allegations of sexual assault could change your life forever.

Tonii Roulston truly cares about the effect on your life before, during and after the accusation, the charges and the trial. Tonii Roulston has tried numerous sexual assault cases winning outright acquittals when other lawyers thought the case was impossible to win.

In a recent interview, Criminal Defence Lawyer, Tonii K. Roulston said, “Accusations of sexual assault are the easiest accusations to make-up, because the so-called victim is automatically believed often times without proper investigation. As soon as this occurs, the accused person should contact a lawyer so that we can start our own investigation and take the offensive.” Tonii Roulston has serious concerns and skepticism regarding the “I believe you” and “Me too” campaigns that may hinder the accused’s right to a fair trial.

Tonii Roulston has defended several violent offences including domestic violence to murder/manslaughter charges successfully with positive results. These types of offences require your lawyer to consider every possible defence due to the seriousness of the charge. If you are charged with a domestic assault, Tonii will walk you through the process and tell you what you need to do to defend the charge and how to obtain a successful outcome, which often results in no criminal record.

Tonii Roulston has successfully defended a wide range of different types of drugs including cocaine, ecstasy, methamphetamine, heroin, fentanyl etc. with varying quantities from small amounts to pounds and kilograms. Even the smallest amount of drugs can affect your life if you obtain a criminal record; it is critical that a drug lawyer who has experience in these matters utilizes every defence available. Tonii Roulston will seek to find a defence to your drug matter that may include: fighting a Search Warrant or Wire Tap; making a Charter Application to exclude the drug evidence; arguing possession, and arguing that the police did not follow proper procedures.

Tonii Roulston has defended a range of murder cases; from the most complicated first-degree murder cases involving firearms, wiretap and undercover operations by police officers; to manslaughters and assaults involving knife fights. Tonii Roulston has defended a murder case successfully where the client was found unfit to stand trial, thus avoiding jail. She has had a manslaughter case withdrawn by the Crown Prosecutor. She has had second-degree murder charges reduced to manslaughter, and another second degree murder charge withdrawn.

In the infamous FOB and FK gang-related homicides, Tonii had 3 first-degree murder charges reduced to 1 second-degree murder. She has defended a conspiracy to commit murder charge that resulted in an acquittal.

In a recent interview, when asked to comment about her role as a Defence lawyer, Tonii Roulston stated: “I have chosen to be a Defence lawyer, not a Crown prosecutor, because I have always believed it is my responsibility as the Defence lawyer to protect my clients from the state and to ensure that their rights are protected every step of the process – sometimes we are all they have”.

Criminal Law Experience

Given her experience, Tonii Roulston is often consulted by organizations and media to comment on developments in the law, including recently in September last year on the Danielle Smith show, she was asked to comment on the aggressive conduct of the Sheriffs in arresting her client while driving a tractor. Tonii stated “the concern is lack of training – if the Sheriffs or Police are to have that kind of power and discretion they need to be properly trained”.

Successfully defending criminal cases involves a commitment to stay on top of new legal developments as well as advancements in investigative techniques. Tonii Roulston’s membership to the largest organization for Criminal Defence lawyers in the United States (National Association of Criminal Defence Lawyers (NACDL)) has enabled her to do this.
