The documentary is on Tubi.tv, a U.S. streaming service that offers hundreds of freebie movies and TV shows. I believe this particular doc can be seen without a VPN in Canada, although other items on the site are U.S.-licenced only. You can watch the 43 minute show here. 

Speaking of Tubi, it's about to get heavily into sports programming, although you won't be able to see many major live contests. These free channels will be viewed-in-America-only but that's why VPNs were invented. 

"The Fox Sports channel on Tubi will include “highlights, daily studio content and original programming,” according to the companies. Tubi’s curated NFL channel will include “near-to-live” in-season digital highlights plus replays of “some of the most memorable matchups in NFL history” and library content including past seasons of the series “Hard Knocks.”

MLB on Tubi features classic baseball games, highlights and shows, including historic World Series and All-Star Games replays, in addition to the “MLB FastCast” daily show.

There will be some actual live sporting events on Tubi, including on the Pac-12 and Stadium channels. Along with the 10 sports channels, the Tubi hub also will comprise nearly 700 hours of on-demand content at launch from the NFL, MLB, Nascar, Big Ten, Concacaf soccer, PBC boxing, PBA bowling and more."
