Here's an answer from another Canadian.
If you want unlimited access to the money, the current 5% from WealthSimple is pretty good. The rate paid may change, going forward, but it's 5% now, when inflation is around 3%.
If you can lock the money in for a year, you could secure a similar rate for that term with a GIC.
With more information (your overall financial picture, how much you want available for a future home, how much you plan to spend on the next home, other goals) you may get more nuanced advice.
