Recent Newmarket Cases & Success Stories

CASE STUDY: Charges Withdrawn – Over 80

Getting the criminal charge of over 80 dropped was the priority. The Highway Traffic Act charges carried fines and penalties, but no criminal record. A plea deal to have the criminal charges dropped would be a fine option that avoided trial and saved the client money.

CASE STUDY: Charges Withdrawn – Over 80

While on his drive home from a charitable event, Mr. B was stopped by police in a RIDE check. He had consumed only a small number of drinks that evening, and they were spread out over several hours, but Mr. B was nervous because he rarely encounters police.

CASE STUDY: Charges Withdrawn- Driving With BAC Over 80

Mr. T’s ability to drive was central to his practice as a butcher. Farmers would contact Mr. T in emergencies where livestock needed to be put down and butchered quickly and losing his ability to travel for work would be financially devastating.

CASE STUDY: Charges Withdrawn – Over 80

This client's trial dates were cancelled and she was free of the burden of fighting criminal charges far earlier than she thought she’d be.

CASE STUDY: Dangerous Driving Plead Down to Careless Driving, Two HTA Offences Withdrawn

Mr. G and Ms. L collided while driving on a residential street. The interaction between the two became heated, and involved them driving side-by-side, shouting at one another from their own cars, and Ms. L alleges Mr. G was tailgating for some time. After the collision Ms. L claims that Mr. G sped off.

Tarinpal was absolutely fantastic! I was facing charges which could have resulted in deportation and possible jail time. He was able to have all my charges fully dropped in the first meeting with The Crown. I am extremely happy with the results and cannot boast enough about how fantastic Tarinpal... has been to work with. He followed up several times, and was quick to respond to any inquiries I had. I would highly recommend more

Last month, a close family member was in immediate need of a criminal lawyer. Within hours of my family member’s arrest, Tarin met with us and made us very comfortable that we hired the right person. For each of our questions—he had answers. Throughout the case, Tarin was very responsive and kept... us fully informed about the case. I always felt like our case was a priority. Tarin advised us about the various possible outcomes associated with the case, and assured us that he would fight for the best possible outcome—which was for my family member to be released on bail and to have all criminal charges withdrawn completely. At every point, I felt that Tarin was in control of the case and confident in his ability to obtain a desirable outcome. Tarin was a zealous advocate for my family member and, in the end, he was able to negotiate to obtain the best outcome—all charges were dropped—and rightly so!It’s never a desirable circumstance to be in need of a criminal lawyer, but life happens, and when it does, I highly recommend Tarin to help you navigate your way to a positive and equitable outcome. Thank You Tarin! I’m thankful that we found more

I had gotten charged with failure to provide a breath sample and like most people in this situation my life had been turned upside down.After realizing the severity of the situation and financial crisis i was facing i knew i was definitely going to need a lawyer.I was debating about pleading... guilty and saving the money but “ If you don’t fight then you definitely don’t have a chance” and I’m glad i did.Keep in mind that trial is always a gamble and may not win. 5 months of hell... stressing night after night.The day of my trial my lawyer Edmund Chan, had found a technicality in my case and referenced it to a previous case that had been appealed and overturned 3 weeks previous. The charge was dismissed.I am extremely greatful for the Aitken Robertson firm and i would recommend anyone in a similar situation to go with them. Worth the moneyread more

I am extremely thankful for trusting Aitken Robertson with my criminal traffic violation in court. It goes without saying that Aitken Robertson will deliver on their promises when dealing with your legal obligations, and will make sure to get you the results you expect and deserve. I especially... appreciated how the team always responded in a caring and timely manner to my inquires regarding my case and related strategies. They made what would have been an extremely stressful situation quite manageable, and even represented me when I physically could not attend initial court hearings. The team and I were able to determine the most appropriate defence strategy regarding my offense, and within only a matter of weeks, a favourable verdict was determined by a judge. I will be sure to recommend this firms' services to anyone of my friends and family if/when the time comes. Thanks again!read more

July 2017, summer weekend at the the cottage when things and the car took a turn for the worse. Early in the am I was involved in a single car accident returning to the cottage. The cars 911 assist had alerted authorities of air bag deployment. Shocked and confused I was arrested and charged with... impaired and over 80. Later that morning we turned to the internet to find a lawyer, having never required one and relying on reviews. We called Aitken Robertson and took advantage of there free call. The call and advice really helped calm our nerves. Living 4 hours from themuskoka’s, Richards team was able to appear on my behalf for my first hearing and set a date for court. Discovery was professional and conducted by phone. Aitken Robertson was also able to send a lawyer to appear with during an insurance statement for which I was very grateful. With the hard work and negotiations Richard was able to work with the Crown and the case never went to court. A lawyer form his Newmarket office was present and helpfully during my appearance with the Judge and Crown. Leaving this terrible weekend behind me for a careless charge I consider a win. The team they have is amazing, quick to respond to emails and calls. Even with never meeting with Richard him self or even going to one of there offices, this is the 21 century. Have confidence Richard and his team have your best interest in mind. Oh ya and be patient, resolved March more

In march of 2017 I made an error in judgement.I was given a bottle of single malt scotch out on the ice of lake simcoe. Instead of waiting until I got home my friend and I had a few drinks while fishing. I had arranged a designated driver for the truck ride home not thinking of my atv ride off of... the lake. When I drove my ATV off of the ice into the parking lot the police were there checking license and registration. I was subsequently charged with Driving with over 80.When I contacted my local business law firm the recommended me to Aitken Robertsen for this particular charge. They said they were the best firm around for this particular type of charge. "They were right". I was referred to MR Edmund Chan. The loss of my license would have been devastating. I met with Edmund and quickly learned what I thought was relevant to the case wasn;t and what I thought was irrelevant was. Edmund has earned the reputation as a tenacious lawyer in the courtroom, and he deserves it! He was able to negotiate a settlement that was acceptable to the crown, the police, and most certainly me. I was able to keep my license and pay a moderate fine. Thank you to the Aitken Robertsen law firm and especially Mr Edmund Chan for his outstanding work in resolving my more
