As many readers have observed, Mr. Morneau will get a huge tax break from his donation to charity, and I expect that it will be arranged that the donation will come from him personally, as opposed to from one of his companies, so that the tax credit is based on the higher, individual  tax rate instead of a corporate rate.  

Also, there is no reason to believe that he won't also be granted an option to repurchase those shares at 2017 prices after he leaves politics.  There are many ways for Morneau-Shepell  'keep him whole', and he is certainly not short of good advisors on executive compensation.
