In 1922, CKAC Montreal was officially inaugurated, with Canadian-born actress Mary Pickford and actor husband Douglas Fairbanks in attendance. The station broadcast in both English and French, having been granted a commercial broadcast license in April. La Presse newspaper owned CKAC.

In 1944, CHUM Toronto was born in the incorporation of York Broadcasters Ltd. by Jack Part. He wanted a radio station to promote the sale of his patent medicine products. It took just over a year until CHUM signed on to 1050 KHz with 1000 watts non-directional, but daytime only. However, the CHUM we all know did not really begin until December 11, 1954, when Allan Waters purchased CHUM from Jack Part.

In 1978, Jack Webster left CJOR-AM Vancouver for CHAN-TV Vancouver (BCTV). "Webster" was scheduled for 9-10:30 a.m. each morning and Jack also made appearances on News Hour during the supper hour. The first interview guest on "Webster" was Pierre Trudeau, which Jack long creditted as being his most difficult interview ever. Jack actually began his radio career at CJOR in 1953, but is best known for his years at CKNW: 1963-72.
