Two fringe candidates ran: Reverend Lloyd Henderson, a former mayor of Portage la Prairie, Manitoba had received one vote when he ran in the 1958 Liberal leadership convention and had also run unsuccessfully for parliament as an independent in the 1960s. He was not a delegate himself at the 1968 convention and would famously receive no votes even though his wife was a delegate. Ernst Zündel, not yet known publicly as a Holocaust denier, was also a candidate but dropped out before the first ballot after delivering a speech to the convention, decrying what he alleged was discrimination against German-Canadians.
