So far, I can't find any coverage of "Hockey Day in Canada" tomorrow.
769 has the SN / CBC tripleheader starting at 3:00 Eastern, but nothing before.
SN's coverage starts at 11:00.
Join us for Scotiabank Hockey Day in Canada on January 29th, 2022

NHL Network is televising an early game from Buffalo, and has the 30 minute SN Hockey Central Saturday at 6:30.
I couldn't find anything on ESPN+.
On another topic, I've noticed ESPN+ has added the 30 minute pregame shows from some, if not all Canadian telecasts.
On the ESPN "Watch" page on their website, you can see coverage starting 30 minutes before gametime.
I've never seen those pre-games on Center Ice.
