Dont worry about restarting any clock on the judgment.
Judgments are excluded after 7 years from the date of the judgment. Exclusion is not based on any other date.
The date of the judgment is fixed by court records, and if anyone were to attempt to "reset" that date, it would be both illegal and clearly shown by court records to be incorrect.
Many publc records get into your credit file by way of private firms hired to research public records. They often do not comply with their requirement to update reported information so as to maintain its accuracy. Since you most likely dont know who reported, I would send a dispute to the CRA, along with documentation of satisfaction of the judgment, and request that the status be updated. They know who reported it, and have the obligation to send your dispute to the reporting party. Let the CRA figure it out.
Now that the judgment is satisfied, the court may entertain a motion to vacate the judgment. Some courts will vacate based on satisfaction of the judgment, while others will require a showing of some inaccuracy in the judgment itself. I would call the office of the clerk of the judgment court and have a chit-chat with them about prior court precedent on such motions.
