What kind of money order should I request from a Canadian buyer?

Is there a certain type of money order or cashier's check I should request from a Canadian buyer? It seems like some sellers request only a certain type for one reason or another.
Thanks in advance.

Yup, international MO in US dollars is correct.
hi Trent!
edit: so as not be a complete doo-doo disturber, Canada Post MO should be just fine.

If that is the case, (I know it is not here), then make sure you get a Postal Money Order, and tell them it is for Canada.
