It used to be listed from early 2020 to December 31st 2020. I don't know why SHAW doesn't just add it to all their TV packages ????
Looking at the updated list of free previews for March I would not be surprised to see Love Nature included even though it is not currently listed. I can't remember the last time HiFi was on a free preview without Love Nature also being on a free preview. Like BBC Earth and the Smithsonian channel those 2 channels always seem to be matched up when it comes to any free preview period. So I'm guessing that Love Nature will be on an upcoming free preview from March 16th to April 30th just like HiFi.
HiFi is being rebranded into BBC First starting on March 16th which explains the free preview.
NHL Centre Ice is on a free preview from March 10th to March 16th on select cable companies. Bell, Rogers and Tbaytel have been announced as having this free preview - no word yet from SHAW.

Just a heads up on the upcoming Crave TV Free Preview ( April 16th to 19th ) : it will just be for the Crave 1 and HBO 1 channels and possibly the Crave online catalog.
May sure looks like a " meh " month for free previews. All I can find is:
Sportsman channel ( May 1st to May 31st )
Sportsnet 360 ( April 30th to May 31st )
Sportsnet One ( April 30th to May 31st )
