“For sure, Brad is not a big fan of the gay lifestyle," Patton said at another point.
Asked to clarify his position, Trost told BuzzFeed Canada on Tuesday that he supports everyone's ability to do what they want in private.
"It's not any of my business. But I don't support a lot of the political agenda that has been often ascribed to the political leadership of the L-G-B-sort of community," he said.
He said he had not yet seen his campaign's video, but did not dispute its message about his discomfort with "the gay lifestyle."
"A gay lifestyle would be people having — how would we put this — gay people having gay sex. That's their business, from my perspective, but it's not something I want to teach my kids is right and moral," Trost said.
Trost said he believes "sex is supposed to be in a committed heterosexual married relationship."
Trost, a former geophysicist, has represented the Saskatoon–University riding since 2004. He is part of the Parliamentary pro-life caucus and one of the most outspoken MPs in Ottawa for a "traditional" definition of marriage.
