Lethbridge Transit System #3 was a 1961 TD-51 built by CCF/Brill. The TD-51 was CCF's answer to the GMC TDH-5301 New Look. The TD-51 was never really a success, and #3 was Lethbridge's only one. However, Lethbridge did not purchase any GM buses (since the TG-3609 #8) until 1965, so it looks like they bought the TD-51 purely because most of the other buses in the fleet were CCF/Brills.
