When you talk about dividends, reliability is very important. For your income portfolio, you want to buy and hold stocks for a long time, and you don't want companies in your portfolio that suddenly stop paying dividends. Enbridge has a very solid track record on this front. It's been paying dividend to its shareholders every year since 1953. This long history suggests that you can rely on its dividend cheques during recessions, oil market downturns, and financial crises. Enbridge is also a great dividend-growth stock, meaning that the company consistently pays more in dividends to help its investors to counter the effects of inflation. Over the past 10 years, its quarterly dividend has grown to $0.47 a share from $0.16. For the next eight years, Enbridge plans to raise its payouts between 10% and 15% each year as its undertakes several growth projects. Suncor Suncor is the largest oil sands player in Canada. Unlike Enbridge, its stock has been more exposed to variation in oil prices.
