Investors with income needs and those looking for the best-quality dividend stocks on the TSX, listen up. These three picks are some of the best historical dividend payers on the TSX. Additionally, I think each of these companies has solid long-term dividend and capital appreciation potential. Here are three companies with dividend yields higher than 3.5% that I think every investor should own as cornerstone holdings in an income-oriented portfolio. Fortis Currently providing investors with a dividend yield of 3.9%, Fortis (TSX:FTS)(NYSE:FTS) continues to be a top dividend pick of mine. Specifically, this is a stock I think investors should own for its dividend-growth potential. Historically, Fortis has raised its dividend each and every year for nearly five decades! Not five years; five decades. This has been one of the best dividend-growth stories out there, making Fortis one of the best Dividend Aristocrats on the TSX today.
