The October monthly Notice to Mariners (https://www.notmar.gc.ca/publications/monthly/east-est-10-21-en.php) was released today and nothing about Cape Race nor DGPS is in it.
However, finally found it in the Navigation Warning (NAVWARN) (https://nis.ccg-gcc.gc.ca/public/rest/messages/en/search?q=&status=PUBLISHED&from=&to=&areas=1&categories=15&sortBy=DATE&maxHits=20) section:

Looks like they just found it on the 28th... its been off long before that.
There are two additional notices:

CCG DGPS Station Cape Norman located at 52 30.00N 055 49.00W on 310 kHz off air as of 282323 UTC Oct 2021.
Position 52° 30.000'N 055° 49.000'W

Didn't receive Richmond here last night, but Cape Norman came in with only about 380 decodes (the ionosphere is a little upset, so hard to say if its due to that and/or if the station is on reduced power).

Thanks for the info. I wonder if they are informally shutting down DGPS?

The future of the CCG Differential Global Positioning System (DGPS)
• Due to its age and the needs for replacement, the CCG conducted an options analysis for the future of the CCG DGPS service.
• CCG will be discontinuing the Canadian DGPS by the end of 2022. All 19 sites will be shut down simultaneously.
• Between now and Fall of 2022, CCG will continue to inform stakeholders and communicate in preparation for the shutdown date.
