Best place to exchange USD or CAD?

Visiting HCM next month. What's the best place, value wise, to exchange USD or CAD dollars? Eh ... thanks

Same answer with the topic "Buy USD":

Go to Mai Van gold shop at no. 1A, Nguyen An Ninh street, opposite to Ben Thanh market,
or its neighbor/competitor: Ha Tam gold shop.

Everyday there are lots of tourists, locals ... buy & sell all kind of currency there.

This come from my travel experience, every time I go abroad, I need to exchange money,
and that is the address I go to.

I've checked several other options, but they usually give best prices (in my experience)
