Keep in mind, Brookfield BGI.UN pays a distribution, not a dividend. Its distribution can be made up of a wide variety of things, including dividends, interest income, capital gains and return of capital. So, make sure if you have this company in a taxable account you are aware of the taxes that you will be exposed to.
In terms of growth, I'd expect BGI to provide the lowest. Over the long term, its hard for a company that pays out this much distribution to drive growth. However, this isn't necessarily a negative. This is an income fund, and it does just that. Provides income.
In terms of Capital Power or Enbridge, both of them are relatively attractive valuation wise. Of note, Capital Power was a former Bull List pick.
If I were to choose one right now, I'd choose Enbridge. From a valuation standpoint it's very attractive right now. Not saying Capital Power is expensive, but it's hard to deny how cheap Enbridge is right now.
