Stock price when the opinion was issued
An ETF to buy? There are so many ETFs, so it depends what you're looking for. XIU offers growth and income for retirees. This is a core holding for any investors. There's also a BMO utilities ETF offering a yield and upside. Also, a Canadian bank ETF from any vendor will give you income and growth, like ZWB-T. An ETF reduces volatility vs. owning individual stocks.
How to increase dividends. These are all the same thing. You get exposure to Canadian large caps. There is no diversification by being in all three. ZWU-T should replace one of them to get utilities including pipelines and telcos and less reliance on the banks. Still Canada so you need international. ZWE-T is the best international dividend payers yielding 7% with a covered call overlay. ZWS-T is the best in the US. These are the two to add to the three. These should be in a registered portfolios if you are retired because there is no divined tax credit.
