There WERE emission specs for diesel engines prior to 2004.
They just became stricter in 2004 (and in several ever-tightening levels thereafter).
This is in the U.S. I have no knowledge of emission specs for Canada. But, with any coach built in the U.S. it will meet the U.S. specs. Yes, perhaps a very, very few exceptions for vehicles that would not be for sale in the U.S or any other country with the same emissions standards.
