I have a couple of small accounts with Wealthsimple, including a TFSA. They are OK.
Sometimes they have issues when they implement a new offering. Case in point: they recently began to offer HISAs (high interest savings accounts).
So I opened a brand-new HISA with Wealthsimple, thinking it would make it easier/faster to transfer funds there first and then from my Wealthsimple HISA to my TFSA. I should have inquired before bothering to open the HISA, because I was told by them after the fact that it would actually be faster to transfer $ from my big-six bank account into my TFSA than from the Wealthsimple HISA.
Maybe they've since ironed out the process, but ... that's counter-intuitive.
I sure hope that when the trading accounts open, it will be instantaneous and seamless to transfer from the HISA to the trading account. Same as it is when I transfer funds from my big-six bank account to the big-six discount brokerage.
I'll be asking questions first, once they launch.
