CF-105 Arrow instead of CF-101 and CF-104
The Avro Arrow would beat the crap out of the Voodoo and Starfighter in pretty much every way, and would be suitable for Canadian service pretty much to the end of the Cold War if appropriately upgraded. The Arrow also might be an option for the RAF here, as its supersonic intercept range was more than twice that of the EE Lightning.
Iran-United States-Canada Affairs
After the Iranian Revolution in 1979, billions of dollars worth of military orders were cancelled after the fall of Shah Reza Pahlavi's government, while at the same time Canada's advancement of its armed forces was moving at a fast pace. Iran sold its fleet of F-14A Tomcat fighters to Canada, but only 33 of the 79 aircraft were received before the knowledge of the Canadian Caper came out and Iran angrily stopped the transfer of the aircraft. However, such was the approval of the Canadians' actions that the United States paid for the other 46 aircraft to be built new and given to the Canadians, though the F-14s would eventually be paid for by Canada. Canada would also purchase the four Kidd-class missile destroyers and 55 F-16A fighters originally ordered by Iran, both of which would see long service in the Canadian Armed Forces.
