Stock price when the opinion was issued
Enbridge wants to buy ENF to simplify their corporate structure. In the States, Enbridge offered a small premium, while in Canada, they offered a premium. He suspects the directors of ENF-T are waiting for a higher premium (or that's what he would do). Pays a higher yield than Enbridge Inc. but lacks the dividend growth potential.
It is fine but why not go to a diversified source of dividends. ZWC-T is a basket of the best of the dividends plus a covered call overlay. You could also go for a foreign ETF but dividends are taxable.
