The CAHA submitted a bid to host the top tier of the 1967 Ice Hockey World Championships to coincide with the Canadian Centennial. Potter advised to host only the top tier of competition which would generate the most ticket sales and felt that the IIHF would be willing to host the lower tiers of competition elsewhere. In March 1965, the IIHF declined the CAHA's bid in favour of hosting all tiers of the 1967 World Championships in Austria. Potter questioned whether it was worthwhile for the CAHA to participate in future World Championships if its relationship with the IIHF could not improve and be financially sustainable.
