The season premiered on March 6, 2019, on Global[1] and ended after 69 days on May 9, 2019, when Dane Rupert was named the winner and Anthony Douglas the runner-up.

When only two HouseGuests remained, a jury formed of previously evicted houseguests decided which finalists win the grand prize of $100,000, a $25,000 home furnishing makeover from Leon's, $10,000 worth of groceries courtesy of Summer Fresh, as well as a dream vacation for two anywhere in the world courtesy of Contiki Holidays.

The Head of Household - who in previous seasons, was guaranteed to play - would not be eligible to compete in the Power of Veto Competition until the Final 5 round.

Damien again won the public vote and, after being led through a series of clues, entered Leon's Secret Lounge and selected video intel on Mark and Samantha.

Big Brother then told the HouseGuests that they would have to unanimously decide who they thought should receive the Blood Veto despite not knowing how it worked.

On the night of the premiere, it was revealed that Canada would vote between two “Secret Assets"[8] to enter the house and become the fifteenth and final HouseGuest.

[10] During the first live eviction episode, it was revealed that Cory was voted in by the Canadian public, but she had to complete a secret mission before officially becoming a permanent houseguest.

She successfully completed her mission by securing three "Final Two" deals in the first twenty-four hours with Eddie, Kailyn, and Damien, making her a permanent HouseGuest.

Among the boxes hid the "Secret Assassin" power which let one person anonymously nominate a third nominee for that week's eviction.

After everyone settled in, Arisa dropped another bombshell: the Power of Veto competition for the week would be voided, meaning the two nominees would automatically face the first eviction.

In the first round, HouseGuests must untie themselves from their chair and use the materials inside the chamber to reach a set of keys to unlock their door.

Cory formed Final Two deals with Kailyn, Damien, and Eddie, thus completing her mission and earning safety for the week.

On Day 8, Kyra and Maki, as well as Adam, Anthony, and Chelsea, splashed in the On a Roll Power of Veto competition.

On Day 15, Damien and Kiera, including Kyra, Samantha, and Cory, gamed in the Instant Bingo Power of Veto competition, sponsored by "OLG".

After following a series of clues, he entered Leon's Lounge for the opportunity to watch classified information on Mark and Samantha.

Throughout the competition, Big Brother will make them offers to lure them away from their button, including pizza and Have cards to avoid being Have-Nots.

On Day 22, the nominees, joined by Mark, Samantha, and Cory, put it all on the line in the Comp Beast Hall of Fame Power of Veto competition.

Eddie and Kiera, accompanied by Anthony, Estefania, and Mark, then got mazed and confused in the Spaced Out Power of Veto competition.

Following Chelsea and Eddie's evictions, the HouseGuests surveyed the scene in the Eye Spy Head of Household competition.

As a reward for winning Head of Household, Samantha earned the opportunity to warch an exclusive episode from "Adult Swim" with a HouseGuest of her choice.

On Day 30, Canada voted for Kiera to receive a one night's sleep on a real bed in the Have-Not room.

Definite cracks formed within the "Pretty Boys" alliance after Adam got fed up with the others wanting to target Samantha.

On Day 36, Dane and Estefania, plus Kyra, Samantha, and Mark, rolled in the Breaking Records Power of Veto competition.

On Day 43, Adam, Damien, Kyra, Estefania, and Cory were grilled in the Bring the Spice Power of Veto competition.

On Day 50, Damien and Estefania, combined with Dane, Kyra, and Mark, mined in the A Miner Delay Power of Veto competition.

In this competition, each HouseGuest will shoot their ball with the giant pool cue towards the numbered slots at the end of the table.

The HouseGuests failed the quiz, but Big Brother revealed it was all a prank, and the Have-Not Room was closed for the season.

In this competition, HouseGuests must carry one crystal at a time down their lane through the water, under the bamboo cage, and onto the floating platform.

On Day 69, after receiving all of the jury's votes, Anthony was deemed the runner-up and walked away with $20,000, and Dane left the House with $100,000, $10,000 worth of groceries from "Summer Fresh", a dream vacation for two courtesy of "Contiki Holidays", a $25,000 home furnishing makeover from "Leon's", and was deemed the winner of Big Brother Canada 7.

In his conclusion, he stated, "Big Brother Canada 7 started with fire before flickering out into smoke by the season's end.
