Processing time depends on your visa office. Vancouver is notoriously slow. Mississauga and Brampton are pretty slow too. Ottawa and Montreal and quite similar. Typically, anything the agent tells is you is a "vague estimate". Usually it is a 5 to 6 months wait for oath after the test. Did you spend time out of Canada for which you submitted a police clearance certificate? I am guess my delay to DM was because of that as the CO said she would "analyze" the PCC that I submitted. They might have independently verified as well.
Today, the ECAS changed to Decision made. May I know what will be the next move? Does it take the same timeline as DM for Oath invitation? Pls advise.
