For English Canada, the destruction of those
planes was a trauma that lasts to this day because
the Arrow represented the height of national pride,
and their destruction the deepest low.
I'm neither Canadian nor Japanese, but there may be parallels to how Japanese felt about the loss of the battleship Yamato (and her sister ship, Musashi) in WWII.
An underdog nation, with pride in "punching above its weight class", placed a lot of hope and pride in a single piece of military hardware.
It was the largest battleship ever built, key to the Japanese strategy in WWII. American battleships' guns and armor were limited by the need for American battleships to fit through the Panama Canal. Knowing this, Japan built the much larger Yamato class with armor impervious to the 16" guns on American battleships. Her 18" guns could cut through any American battleship with ease. The Yamato was really a marvel.
Of course, it was utterly useless in battle against the American navy. Its WWI-era fire control systems were decades behind those of American battleships, especially the Iowa class, and of course more importantly WWII showed the world that battleships were helpless against naval air superiority. The Yamato was sunk by American planes, having never fired a shot against an opposing battleship.
The Yamato has remained in Japanese imagination, though, most notably in the long-running anime Uchu Senkan Yamato / Space Battleship Yamato / "Star Blazers".
