I get the Short Interest spreadsheet from TMX but it's only every 15 days. Below is what it looks like for Jan 31/24. It is a subscription service. I was unaware that it was possible to get it daily or hourly.
Going back to mid 2022, there seems to be a consistent short interest of 120,000-160,000 on FFH-T. 20,000-40,000 on FFH.U-T. Without considering @sleepydragon's input, I might have concluded that someone has had a short position in FFH for a while now. I'm not so obtuse to think I could be wrong about the short interest being published more frequently. If @sleepydragon could point me in the right direction, I would be grateful.
