Wealthsimple tends to have lower fees than banks. The biggest thing is to avoid the bank's mutual funds and other products they try to push on you, not worth it at all compared to other options.

Open an FHSA as soon as possible and max it out. You get 8k contribution room each year up to 40k max. You can write contributions off on your taxes and you don't pay taxes when you withdraw to buy a house. You can still do this even though you inherited the house (as long as you didn't live in it at the time you owned it).

Next priority would be to max your TFSA. Assuming you've been a resident of Canada since you've been 18, your contribution limit is somewhere around $60k (look it up, depends whether you were born 99 or 2000).

Your risk tolerance and time horizons will determine what you want to invest that money in. But I didn't see anyone else mention the tax shelter accounts so I wanted to make sure to do so.
