I guess you mean Managed Payments which is a return to the status before eBay was forced to sell off Paypal which it bought in 2002. Paypal was only a sub-contractor from 2015 to 2020, with a slow changeover.
You haven't been selling for over a year, which makes you a returning /occasional seller. I suspect one of the changes eBay is making is a demand for better verification of identity for sellers if only to hold off scammers and account hijacking.
You will need a Canadian chequing account.
- It can be in loonies or in US dollars.
You will need to verify your identity. Since I have been selling steadily I may have had a slightly easier time, but I still had to set up bank accounts.
- Some sellers opened new dedicated accounts for online selling, often online.
The micro deposits don't work very well in my experience.
I used passports to verify identity, but driving licenses are also accepted.
On one account I was asked for a bank statement on letterhead. Note that the Royal Bank don't do that anymore. (Grrrr.)
I think if this was in fact planned, that a lot of it is supposed to be difficult, just to discourage criminals. That it also discourages honest sellers is a bonus accident.
And all your documents must match. If your name is John Jacob Jingehiemer Smith and your bank account is as JJ J Smith and your eBay is John JJ Smith and your passport is John Jacob Jingehiemer Smith , you will have problems.
