Except that Low Power TV stations (Non-Class A; and often abbreviated as LPTV), and Translators, are independent of the phases prescribed by the FCC. Also, Canada's repack schedule has 14 phases, with the last one concluding 1/14/2022.
Regarding the US non-phased transitions: "LPTV and TV translator stations may remain on their existing channels until they are needed by repacked stations or for those stations in the 600 MHz Band until they are notified by a new 600 MHz Band licensee that it is ready to commence operations or conduct its first field application (FFA) testing." (https://www.fcc.gov/about-fcc/fcc-initi ... transition)
My quick Googling isn't finding a hard and fast end date for these frequency changes. I did find this notation about how analog broadcasting is still being allowed into next year: "12 months after the completion of the 39-month transition period, or until July 13, 2021". (https://docs.fcc.gov/public/attachments ... 6300A1.pdf Specifically, bottom of the PDF page 7, numbered as page 6, in footnote 27.)
I'm not in the Detroit area, so I can't comment on whether any LPTV broadcasts will remain above RF36 in your area by the end of this month. Perhaps maybe one Canadian station, per what I see on the RabbitEars.Info site?
In West Michigan, there's one analog still going (the 3 Angels station in GR), using RF48. They have an approved Displacement Construction Permit to go digital on RF27, expiring in July 2021. Their analog broadcast coverage is quite small, and doesn't reach me in eastern Kent County--so I can't confirm if they're still on the air now or not.
In the Traverse City area, the WWTV Digital Replacement Translator (DRT) apparently is still on RF40, bathing the bowl of the city from on Hickory Hill with CBS/FOX/etc. WPBN saw through getting their two DRTs under RF36 in the last few months. Also, I believe the one analog (WXII-LP on RF12) is still chugging along, but with an approved Digital Companion Channel Construction Permit for RF30 valid into July 2021.
The only constant is change, it seems!
