The micro deposit system of confirming identity doesn't work very well.
I've seen it posited that the problem is that US currency is being sent to Canadian bank accounts and the foreign exchange is fouling it up.
Most Canadians don't like to use our SIN for identification and eBay has been told they can't demand that. But members can voluntarily use it if they like.
I used my passport (the picture is actually not bad) and DH used his driving license.
FWIW - Two of my accounts had a lot of problems in the setup, but once those were fixed, the payments that had been Held were promptly transferred to the appropriate banks.
The social media people are employees , well trained and were very helpful in the months it took to clear the problems.
