Notable Cases

David Vaughan has an impressive record of securing significant victories for his clients. Here are some highlights of his most notable cases.

Pham v. Qualified Metal Fabricators

David and Partner Jon Pinkus secured a groundbreaking and precedent-setting win. They successfully argued that their client’s silence during a temporary layoff, even after multiple extensions, did not amount to consent.

Mazanek v. Bill & Son Towing

In this case, David represented a 44-year-old tow truck driver who was misclassified as a contractor and terminated for cause due to serious allegations of theft. The court found the employer’s allegations unproven and its main witness not credible. Mr. Mazanek was reclassified as an employee and awarded six months of severance and back vacation pay.

Czerniawski v. Corma

David’s client, let go for cause after 19 years in the manufacturing industry, was awarded 19 months’ pay plus 10% for benefits. David successfully argued that the employer failed to explore other disciplinary options and could not fire the employee without severance pay.

Alarashi v. Big Brothers Big Sisters of Toronto

David’s client received only four weeks’ severance pay after four years of employment. David challenged the termination clause in the client’s contract and secured a substantial increase in severance pay.

Fillmore v. Hercules

In an important case at the Ontario Court of Appeal, David successfully defended his client, reaffirming that the duty to mitigate is not triggered unless the employer re-extends an offer to work out the notice period after the initial termination.

Carpenter v. Brains II, Canada

David’s client, terminated without cause after 18 years of employment, was initially given eight weeks’ working notice and 18 weeks’ severance pay. David argued that the termination clause was unenforceable, securing a substantial increase in severance pay for his client.

It is always stressful when you have to deal with severance package questions but David provided wise counsel and great advice. He clearly knows what he is talking about and he was extremely responsive and prompt and walked me through the whole process so that any outstanding issues could be resolved quickly.

I found David to be very qualified and professional. Even when he was busy, he took the time to address my concerns, which is one thing I believe a client needs most. I was worried his charges would be high but was pleasantly surprised to see they were very reasonable. I would highly recommend David.

I was constructively dismissed from my employer of 9 years. I made the decision to seek legal advice to learn about my option. I spoke with David Vaughan who connected with me on a human level. The result ended with a better than expected settlement. If it wasn't for Dave, I would have continued to believe that the employer is always right!
