iTrade and Brookfield Companies

I am trying to resolve an issue whereby I was not paid my last distribution from Brookfield Infrastructure Partners in US dollars, even though I hold my shares on the US side of my iTrade account. After many conversations, the customer service people are all telling me that because I am a Canadian resident, I must be paid the distribution in Canadian dollars (which they have converted back into US dollars, while taking their cut for a FX fee). They say this is the case for all their customers holding Brookfield stocks.

I would like to fact check this assertion. If you are a Scotia iTrade customer (Canadian resident) who holds shares in a Brookfield company on the US side of your account, would you let me know please if you receive the original US distribution amount, or some converted (and lesser) one?

I should also point out that I own other Brookfield companies in a competing brokerage, always on the US side of my account, and I have never had an issue receiving the original US dollar dividend.

Thank you in advance.
