CASH.TO Alternatives - Emergency fund

Hey everyone,

I’ve been doing some thinking about the best place to park my emergency fund, and I’d love to hear your thoughts! Right now, I know that a lot of people swear by ETFs like CASH. TO, but I’ve been looking into alternatives like PSA and ZST.L.

From what I’ve seen, PSA and ZST.L seemed to offer a better return, at least last year (though I totally get that these things can change). It’s tempting to switch, but I’m wondering if I’m missing something important here.

For those of you who’ve explored this, do you think it’s a good idea to move funds around for a slightly higher return? Or is it better to just stick with the “safer” options? I know stability and liquidity are key for an emergency fund, but I also don’t want to leave too much on the table.

Would love to hear your opinions, experiences, or any advice! Thanks in advance to this amazing community.
