I agree completely with John Heinzl and I have proof.  
The other day I was looking back to old RIF statements.  The RIF is 15 years old and I was looking at Income Trust holdings.  Some of you may remember those.  The RIF held Enbridge, TransCanada and Interpipeline, among many others in 2007.  ENB and TRP were sold to buy Pembina because it was cheaper and I could buy more to get more dividends.  Just as an example, I still hold IPL since about 2006 when I bought !,000 shares for $8.44 each.  At the time it paid .07 cents a share monthly.  I still have 1,400 shares paying 0.135 cents each monthly for a continuing payout of $2,184- per year.  I still also have 1,200 shares of Pembina and many others but IPL is my oldest, continuous holding.  It shows that buy and hold dividend stocks do pay off and provide an on-going income.  Yes I could sell and make all kinds of capital gains but then I lose my dividend income based on the money spent to buy them..
