FYI, the last mention of "Second Chance" in a Bell Media press release was the announcement of the Canada's Choice fan vote, March 21st.
"The Canada’s Choice team won’t be the only ones looking for a second chance on THE AMAZING RACE CANADA. They’ll be joined by a group of new racers who have overcome challenges and faced reinventions and transformations. Now, they’ll all have the opportunity to experience the race of a lifetime."
