Big Brother Canada, Global – 2-hour finale
A drama-packed two-hour finale will crown a winner of Big Brother Canada Season Three.

Bahama Blue, Love Nature – “Coral”
An amazing underwater metropolis; the biodiversity of the reef is critical to species living in the Bahamas. Diverse and colourful marine creatures seek food and shelter among the complex coral structures in this interdependent environment. Every day they negotiate and to share the space and interspecies interactions abound. Schools of cleaner fish whom preen their neighbours in assigned cleaning stations or quick twists of fate can turn the predator into prey.

MasterChef Canada, CTV – “The Trip to Bountiful”
The final four home cooks arrive at a beautiful Niagara vineyard for their next challenge, where they learn they’ll be cooking for their lives with the bounty of the area. Each home cook must create a restaurant-quality plate for the judges and the 18 local farmers who supplied them with their fresh regional ingredients. The winner of the Niagara challenge automatically moves forward to the finale, and one home cook is asked to leave the competition. The remaining two finalists cook off in a Pressure Test where they must replicate three magnificent chocolate desserts.

Survivorman: Finding Bigfoot, OLN – “Survivorman Bigfoot: Texas/Utah”
Les begins his search in East Texas, invited onto private land by a local who claims to have experienced the Bigfoot phenomenon for over 35 years. Locals’ stories lead him to the remote mountain terrain of rural Utah, where ungodly screams and tales of haunted hollows find Les camped out in a canyon way off the beaten path, firmly planted between skepticism and acceptance. Lacking irrefutable evidence, Bigfoot is just a contradiction – a 10-foot monster that he can’t find.

Big Brother Canada, Global
It’s Eviction night in the Big Brother Canada house. Who will be sent packing? Who will become HOH?

Bahama Blue, Love Nature – “Mangroves”
More than a tangle of roots growing out of swampy muck, the Mangroves are nurseries for the marine life of the Bahamas. More than 90% of the species of the Bahamas spend some part of their lives here. This is where baby sharks learn to hunt and young lobsters learn how to hide. The roots of these salt-water tolerant shrubs are also home for some remarkable creatures: from the tiny seahorse to the resilient tree crab. Even the iconic Flamingo gathers here to feed on the crustaceans that give them their pinkish hue.
