I know that CASH.TO is terribly trendy, but I also want to remind you that there are alternatives!
HISA.NEO, NSAV.NE, PSA.TO, and CSAV.TO work exactly the same way and may even offer a slightly higher net rate after fees.
There's also HSAV.TO, which reinvests the interest rather than distributing it, effectively converting it into capital gains. However, due to a technical reason, it is currently valued significantly above its true value ($0.46 as of this morning). It could be a smart fiscal move in the medium to long term, but I don't recommend it unless you fully understand how it works and what you stand to gain or lose.
It would still be convenient to have a generic name to group these ETFs together...
PS: I included links to the issuers for each ETF for those who are curious.
