Kyle Rozendal was ejected (Day 19) after "racist behaviour" a call production had valid grounds to make and thus the ejection.
However, before Kyle was ejected... Jamar Lee was ejected "(Day 17) for threatening Kyle and therefore production intervened and made the call to eject him.
These are the most controversial events Big Brother Canada has ever had. Aside from a house guest exposing Alec Beal during season one when Alec had the shower door opened on him. Alec thought he was exposed over the live feed, but production didn't let that happen.
