In this case, the employer argued that Mr. Drysdale, a warehouse worker, was not “management” and therefore he was entitled to lesser overall severance. David defeated the employer’s argument. The court awarded his client 22 months of severance pay.
Patterson v. IBM Canada Limited, 2017 ONSC 1264 (CanLII)
After many years of loyal service, IBM terminated our client who was an IT Specialist. David successfully challenged IBM’s severance offer, and was able to obtain an award of 18 months of pay and benefits for Mr. Patterson.
Summerfield v. Staples Canada Inc.,
2016 ONSC 3656 (CanLII)
Staples refused to provide proper severance pay to our client, a 39-year old enterprise account manager with less than 5 years’ experience. David was able to get his client 6 months’ full compensation (more than 1 month per year of service).
Jackson v. M.N.R., 2006 TCC 614

David successfully argued two appeals against the Ministry of National Revenue, at the Tax Court of Canada, proving that an accountant whom worked for her spouse (a doctor) was employed in insurable employment.
