Frankly whoever wrote this review seems to have no clue. Canon's 32.5 MP APS-C sensor has been their best APS-C sensor in terms of noise compared to their older 24MP sensors and its not much behind Sony 24MP and Fuji 26MP sensors at high ISO. You can check for example Canon M6 Mark II (32.5MP) vs Canon M6 (24MP), Sony a6400 (24MP) and X-T4(26MP) on dpreview studio comparison tool:

You beat me too it. ;-)
First the unreferenced quote in the post you replied to seem to be from this "TechRadar" overview. Not exactly where I'd look for definitive camera reviews and testing. In fact, in the article they also write:
"We had less than an hour with the EOS R7 in tricky shooting conditions at an indoor ice rink, so it's too early to make any firm conclusions about its image quality. We also haven't yet been able to examine its raw files, because these aren't yet supported by raw processing software. But it is possible to make some broad observations about its 32.5MP sensor."
So, this non-photography site... shot with it for less than an hour... at an ice rink... entirely in jpg mode.
Ahem.
The quality reviews of Canon cameras using the 32.5 MP 1.6x cropped sensor are quite positive, and most laud its noise performance among the things.
This is in line with the past two decades of sensor development, where the high resolution version of a sensor in one generation typically has better noise and dynamic range performance than the previous generation of that same sensor type that usually had lower resolution.
The fear that a new, higher MP sensor is going to produce worse noise and DR performance is one of those myths of digital photography that stubbornly sticks around despite all the evidence to the contrary. We have heard it stated authoritatively at _every_ juncture where a higher resolution sensor with newer technology was introduced. If it were true, by now, when we've gone from 3MP and lower early sensors to (in this case) one that has 10x the number of photo sites, the performance would be abominable.
I guarantee you that it isn't, and that it is better in every way than the older generation of lower-MP sensors.
Let's make an assumption for a moment: the rumored 40MP Fujiflm APS-C 1.5x (larger than the Canon sensor, BTW) cropped sensor uses an unstacked design. It is virtually certain that in the worst case it will equal the previous 26MP unstacked sensors used in earlier Fujifilm cameras in terms of noise and DR and improve on potential resolution.
It isn't going to be worse.
