I agree with John on this because I bought 700 TRP @ $22.19 in Apr 2002 when it paid 25 cents a share quarterly and topped up to 1000 by buying 300 in June 2004 @ $25.97 when it paid .29.  I also owned ENB.  I sold 500 TRP in Dec 2006 @ $40.10 each and the remaining 500 in Jan 2012 @ $42.00 each.
I replaced TRP with Pembina (PPL) at half the price so that I could get more shares that paid monthly instead of quarterly.  I also replaced ENB with Interpipeline (IPL) for the same reason.
Now I received $204 and $192 a month in dividends from these two.
If John could do some comparisons it would be interesting and helpful because there are sector choices to be made here.
