The scene involves Jack Harkness with another man, leading some to speculate that the BBC is censoring gay content, though they contend that it is purely due to the explicitness of the scene.
Indeed, the previous three series which aired on the BBC and its affiliated networks featured male/male kiss scenes with Jack, but nothing explicit involving either gay or straight couples.
John Barrowman, the actor who portrays Jack is not happy with the decision. As he told the British paper The Sun:
“You go back into history with Jack and you discover an integral relationship that is part and parcel to what is happening. It’s a massive story.”
According to this article on Xtra.ca, Space will air both versions in Canada:
The BBC edits of Torchwood air in Canada on CTV’s Space network on Tuesday nights at 8pm but Renee Dupuis, communications manager at Space, assures that the Canadian network will also continue to run the uncensored Starz versions on Saturdays nights at 9:10pm, so those deprived of seeing Barrowman and Casey go at it this weekend can check it out Saturday.
