I see your point but their website states:
"You are responsible for determining any and all taxes assessed, incurred, or required to be collected, paid, or withheld for any reason in connection your use of our software and services (Taxes). You also are solely responsible for collecting, withholding, reporting, and remitting correct Taxes to the appropriate tax authority. We are not obligated to, nor will we determine whether Taxes apply, or calculate, collect, report, or remit any Taxes to any tax authority arising from any transaction.
We will report payments and other information to regulatory or government authorities as, if and when required by laws applicable to us."
First they say, we have to report our own and then in 2nd para they say they will report?
"when required by laws applicable to us"
IMHO it's not logical in Canada that they would be required to report it to CRA.
I know in the case of contractors working for and in USA companies, the company must report self employed persons payments, AKA 1099. But that is not the case in Canada.
More than likely a USA catch all just in case they would be required.
