Some of the posters are offering advice which, in general, is correct but not always. Posters on DIS generally book domestic flights to Orlando. Those flights can, and probably should, be booked directly on the airline's website.
Sites like Kayak and Google flights list some combinations which can't be easily booked, and sometimes can't be booked on an airline's site. Sometimes they list consolidator fares. Sometimes they list one way fares on different airlines which can only booked R/T through a third party site. This is rare with domestic flights but not with international. I wouldn't do it unless the savings were large. Different people view savings differently. Saving a few dollars is enough for some.
I googled Hahn. Hahn isn't a broker or travel agency. Kahn only sells B2B, business to business. Kahn is a (charter) airline. They have ticketing agreements with many partner airlines. They are able to issue multi city, multi airline iteinearies on one ticket. All ticketing is done via the TA. Again some of the iteniaries listed on sites like Kayak and Google Flights can only be booked through third parties.
to the OP This is the link to Hahn's webiste regarding changes.

The link got parsed. Indicate you're a passenger, go to the FAQ section on changes. Hahn defers to airline and TA (Expedia) policies.
I have no doubt the Expedia customer service rep has no idea how to change such a ticket. As long as each segment you changed is covered by the airline's waiver policy you should be OK. I'd be comfortable using the verbiage on the website I posted as the basis for a credit card charge back, if necessary.
Airfare from cities like NY to Orlando is very compettive. I'm not so sure air from Montreal is a competitvie. Some posters in Canada drive to US airports in Buffalo and Albany. It's possible the booking made by the OP resulted in real savings.
