Severance Package

I live and work in Mississauga, Ontario, Canada. I am 52 years old, have 32 years of work experience, 20+ years in sales. My boss recently asked me if I was happy in my current sales job (I said I was but I’m not) and said if I wanted out he’d give me a package. I’m one of the top producers and currently make $90K in salary, $10k in bonus. I’ve worked for Company A for 8 years, but was not always on a salary. I was on straight commission for the first 4 years, then switched to salary plus bonus the last 4 years (to even out my pay fluctuations). Company A employs me, and all the sales reps, and owns the accounts, for Company B. Company B makes the products that we sell. In essence, a lot of people’s jobs at Company B are directly impacted by us reps, at Company A, and vice versa. And because of this, each company’s employees must work together to achieve results, but lately the employees at Company B are affecting my sales (which is why I’m not happy). My boss and the President at Company B talk regularly-ish to ensure everyone is contributing. And I’ve been told, changes to personnel at Company B are going to be made in Sept. Given my age, work experience and achievements with Company A (and B), if I were to leave and ask for a package, how much severance would I be entitled to? What amount would be considered a reasonable package? Would I be given more if they “forced me out?” Given my employer is Company A, but my sales directly impact Company B, could I be compensated from both companies or only Company A?
