There's a lot of different types of companies with a lot of different types of balance sheets, and within different phases of their overall lifetime. All those things you've listed are ones that have existed for the last umpteen years, are profitable, paying dividends, dividend growing. This is basically "dividend aristocrats", s&p has an index for that , SPTXDV. G&M provides a free component listing :

CDZ.TO from ishares tracks it... it's yield is \~3% , so less than your 5-6% you quote, and, if you look at the tax documents for CDZ, to get that yield, half the distributions are capital gains, meaning the fund managers are realizing capital gains of the holdings in excess of the dividends received from the holdings (0.002 div vs 0.003 gains; per share, per day)
Nobody is looking at yield. If you want a flat yield, buy bonds. You can find corporate bonds that pay 6-7% easily. The reason people don't do that is because the value of the equity of the relevant company will grow in excess of money paid out of the bond during it's lifetime (and, indeed, company's dividends as well). You can get that 6-7 yield, but the underlying principle is just cash, it *can't* grow.
All that said, dividend reinvestment strategy is still valid, but you need to filter which companies you look at. What dividend aristocrats doesn't see is companies that have just started their journey to profitability & commenced dividends recently, those that and have a stable dividend that hasn't increased, or cases where a dividend was suspended and reinstated. It takes *years* for a company to show up under this criteria and it's easy to slip up.... RSI and SIA both have respectable yields, been paying out years, but haven't *increased* for 5 years. CRRX just started paying dividends a quarter or two ago, so it doesn't show.
If you've only found those 4 general classes of companies, I don't think you're looking hard enough? Those companies I've listed are consumer staples & health... Of course, those categories DO have some good companies, of course, but there are A LOT of companies out there. It's obviously risky to try this, invest in *any* company directly for it's dividend, which is why many don't. Way easier & often more lucrative to just do passive ETF index approaches. If you want cash-money, look at covered call etfs, not a dividend paying company... lmao

RIP to my friends that have Telus stock in their compensation even though they work in the telco or health side of things… but have also been there 12-15 years.
But it may be an opportunity to get a generally diversified stock at a non-bubble valuation.
Shopify is negative over 5 years, so take that as you will.
Copper - Rio Tinto I up like 30% or something over the short term. So be careful that freight train may have already left.
We’re not small on Aerospace here in Canada, either. Those are more military / communications / travel sectors. Planes, rockets, rocket launch pads, satellites, satellite communications, armoured personnel carriers, ships (including ice breakers for the Northern Passage), tugs for guiding / captaining ships in and out of difficult passages (think Churchill, Kitimat). We’re planning on doubling our power grid over the next 10 years - that’s a LOT of copper. Pipeline from Alberta to BC = steel, oil producers, 5 large LNG plants making us one of the biggest LNG suppliers from I think 5 of the 10 largest facilities by 2040 in the world… and who knows if Smith/Moe/Ford can bully Kinew into a pipeline going east tp Central Canada. That’d be a lot more steel, some forestry work to be done, etc.
We’re not only 100# in on data centres. And our data centres aren’t so much about displacing workers as much as they’re about keep our data in Canada, like your medical files, imaging data from MRIs and CAT scans and mammograms… and then augmenting the government to get wait times for everything down - taxes processed in minutes not weeks, forms submitted being processed in days not weeks, applications getting done in weeks not months or years.
