Nick Nobody works as an accountant at an accounting firm. The accounting firm assigns Nick to handle the financial affairs of one of their lucrative clients, Howell Enterprises. Nick promises client, Thurston Howell, a tax refund. Instead, Mr. Howell receives a Notice of Assessment from Canada Revenue Agency, advising that his business owes over $1,000,000.00 in unremitted retail sales tax and a 25% penalty for this oversight. Mr. Howell is angry and wants to sue Nick for his incompetence. Which is the correct tort?
