There's actually a very understated impact of the Arrow saga on Canadian politics. Diefenbaker regarded the project with considerable skepticism, in part because of the costs and the likely lack of benefits, but also because it was an initiative of the previous Liberal government. When he dropped the axe, though, he was genuinely shocked by the anger from Torontonians as a result from the firing of all Avro Canada employees who worked on the aircraft, which played a part in flipping the city from being a Tory stronghold to a Liberal one. After that, he swore not to make decisions with such magnitude without consulting public opinion and using it to judge a course of action.
This backfired on him spectacularly during the Bomarc crisis a few years later. Diefenbaker's Secretary of State for External Affairs Howard Charles Green was avowedly against nuclear weapons, and he clashed with Minister of National Defence Douglas Harkness while Diefenbaker tried to kick the issue down the road. While Diefenbaker did correctly judge that public opinion was not particularly favourably to deploying nuclear weapons on Canadian soil, his demurring led him to incur the wrath of President Kennedy, with whom he did not get along with, to say the least. Long story short was that Washington suspected Ottawa was weaseling their way out of defence and NATO commitments, and after Harkness resigned and Diefenbaker called an election, sent generous funds and staff to support the Liberal campaign, as Pearson, despite being also anti-nuclear in principle, did support continuing with the Bomarc deployment.
