Congratulations!
A DM without any hint of an issue is always a positive decision. If there were an issue, you'd have been told so and given an opportunity to respond.
What this means is that the paperwork (COPR) is in the mail. All you need to do then is present yourself at a Canadian Port of Entry prior to its expiration, initial two places on the form (no undisclosed children or spouses and no undisclosed criminality) and sign the bottom. If you are importing goods you present them your B4/B4a forms. They do a bit of magic in the computer and stamp everything and voila! You are done. You keep one copy of the COPR, they send the other to Sydney NS where in a couple months they produce your PR card and mail it to your Canadian address.
Note that you won't NEED your PR card to get into Canada. CBSA is fine with just your passport and the COPR and airlines will let you fly without it because you are visa exempt. If you plan on transiting the border much, get a Nexus card. If you HAVE a Nexus card, stop into their office and update your records (I added my COPR first and when I got the PR card I updated it with that).
