If you look at this link: http://www.ontariocolleges.ca/SearchResults/CAREER-PREPARATION-MILITARY-ARTS/_/N-lqi4, you will see that some Ontario Colleges DO offer it as a full-time, not on-line program. Your best bet is to contact the college directly to inquire.
For the most part, the required courses are not specific to the DMASc program and therefore it should be viable to take them in full-time attendance at a college. I can't say for sure, but you will most likely have to take the RMC courses online though, as you need to register with them as a visiting student.
I am 5 courses away from completing the program part-time online. If you have any questions, there are a couple of threads on the site with details. But feel free to PM me as well.
