Top Five Money Engineer posts of 2025

The Money Engineer launched in January 2025 and according to the WordPress stats, I made 144 posts last year. What were the most viewed posts of 2025?

5th-ranked post of 2025: ZGRO versus ZGRO.T

I got wind of ZGRO.T through Reddit, specifically r/CanadianInvestor. ZGRO and ZGRO.T are both all-in-one asset allocation ETFs from BMO, but with vastly different yield characteristics. I was confused, but in the end, decided that ZGRO.T was probably not a bad pick for use in a RRIF account as it might save you the hassle of selling shares. Their TOTAL returns (assuming all dividends are invested) are effectively identical.

4th-ranked post of 2025: Spousal RRIF Attribution Rules

I think I was first warned about this nuance of spousal RRSPs/RRIFs by my DIY neighbour (thanks, Steve) and is the main reason I’m only drawing RRIF minimum for the next two years1. I think most of the visits to this article were search-driven. Either that, or people came to admire what might be my favourite article thumbnail2 I’ve posted thus far.

3rd-ranked post of 2025: Norbert’s Gambit with Questrade

As someone who holds more USD-denominated assets than might be wise, I do very much appreciate the existence of a cheapskate way of converting between USD and CAD assets. I think I first learned about this trick via The Loonie Doctor’s blog. The #3 blog entry explains how it works if Questrade is your broker. I would also recommend https://moneyengineer.ca/2025/08/21/tracking-norberts-gambit-costs-with-questrade/ for a very clear picture of what it actually costs (in time and fees) to execute the Gambit: in three of four instances, the time delay of executing the gambit has worked in my favor as the FX rate has drifted a bit to my advantage.

2nd-ranked post of 2025: TD versus iShares all-in-ones

I’m a fan of all-in-ones (and am a little sad https://moneyengineer.ca/2025/01/21/why-you-can-fire-your-advisor-asset-allocation-etfs/ didn’t crack the top five last year). I am genuinely puzzled why people seem to get so wound up about which family of all-in-ones to choose3. I examined TD’s only because their cost to own is a bit cheaper than iShares (who I use primarily), and I’m a cheapskate. (I studied the cost of owning an all-in-one here.) Anyway, in the end, the biggest difference is visible in TGRO versus XGRO because TGRO, unlike any other GRO ETF, uses 10% bond allocation and not 20%. This gooses its return a bit, at the cost of additional volatility. Otherwise, it’s a case of tomato/tomahto. Pick one, or pick them all, it doesn’t matter much.

Top ranked post of 2025: Mini-Review of Optiml.ca

This was, as the title implied, a quick review of a made-in-Canada tool to help craft a retirement plan. And again, my DIY neighbour gave me a heads-up about it4. It got a lot of interest, probably because the kind folks at Optiml linked to my review from their website ;-). I was impressed by the completeness of the tool during my test drive, and it seems like a good and fairly priced way for a DIYer to do some validation of their retirement plan. Having validation of my plan was one of the ways I knew I could retire.

Looking forward to seeing what the 2026 list might look like! Got a topic or question? Send it along to comments@moneyengineer.ca, or comment below!

Mini-Review: Optiml.ca

My fellow DIYing neighbour gave me a heads-up about this made-in-Canada retirement app and so I set up an account an gave it a whirl.

Optiml.ca helps you to “build and customize your financial strategy, stress-test different ‘What-if’ scenarios, or simply confirm you’re on the right track.”

Setting up an account was very easy since it supports integration with Google credentials. And they offer a fully-enabled trial for 14 days without requiring a credit card, which makes things even easier. I chose their most popular plan, the Pro Plan, which is $199 a year1.

The interface is clean and easy to navigate. I was able to get started right away without bothering with the offered tutorials.

I chose to set up the parameters of my current retirement savings manually, but it wasn’t difficult. You could instead choose to link with Wealthica and populate this sort of information automatically. I don’t use Wealthica myself, but perhaps I’ll give that a look in a future post.

Once your data is entered, you can run a “standard” scenario which is what a retirement planner would generate. This is table stakes for any tool, including some of the ones I mention in Tools I Use.

But it looks like Optiml goes much, much further in its analysis. You can ask it to auto-generate scenarios based on historical returns and different inflation rates to see how likely your plan would succeed, and you can choose other objectives, like maximizing spend or maximizing your estate value. You can also ask it to model the three phases of retirement where spending varies as you get older (aka go-go, slow-go, no-go23). You can ask it to play with CPP/OAS start dates, and so on. It seems quite comprehensive and well thought out. And what I really like about it is that it has pre-canned scenarios so you don’t have to think about (and overthink about) each and every input into the model.

And you can save your analysis on the tool itself, which is handy for comparing outcomes and trying different “what if” scenarios.

I encountered what I thought were some bugs in the system, but online support quickly set me straight with prompt, detailed, specific and accurate answers, which is highly unusual in the Canadian financial services space 😉

All this to say, I’m pretty impressed with what I see here. At this point in my retirement, I don’t see the need for it myself4, but for others who are still looking for a tool to help guide retirement spending, this looks like a winner.

  1. Given what this tool can do, this seems a more-than-fair price to me; the cost of a fee-based advisor (who is likely using a similar tool to generate the output) is a lot more than that. ↩︎
  2. This model, according to Google, is attributed to Michael Stein, author of “The Prosperous Retirement↩︎
  3. …and while intuitively this is something that makes a lot of sense, it’s the first time I’ve seen it called out so explicitly ↩︎
  4. In other words, I’ve passed the analysis phase and am just trying to enjoy retirement 🙂 ↩︎
