98 rooms, one bankruptcy, one classified wartime operation
Casa Loma
Built by a Toronto financier who went spectacularly bankrupt within a decade, Casa Loma spent World War II hiding a genuine military secret behind a one-dollar padlock.

Casa Loma is the closest thing Toronto has to an actual castle — and its real history involves both one of the largest personal bankruptcies in Canadian history and a classified military operation the public walked past for years without knowing.
Built by a man who couldn't afford to keep it
Financier Sir Henry Pellatt built Casa Loma between 1911 and 1914 — 98 rooms, $3.5 million, roughly 300 workers. Less than a decade later, in 1923, Pellatt went personally bankrupt in a collapse serious enough to take down dozens of banks with it and prompt the federal government to introduce new banking safeguards. He and his wife were forced to sell the castle; the City of Toronto took possession of it in 1933.
A secret sonar factory (1944)
What most visitors still don't know: in 1944, the Royal Navy secretly installed an assembly plant for ASDIC — an early sonar technology used to detect German U-boats from up to 8 km away — inside Casa Loma's former stables. The entire operation, essential to protecting Allied convoys crossing the Atlantic, was hidden behind nothing more elaborate than a one-dollar padlock and a sign reading "Construction in Progress — Sorry for the Inconvenience." The secret held for the rest of the war.
A tourist attraction since
Since the mid-20th century, Casa Loma has operated as one of Toronto's major tourist attractions and event venues — a genuinely unusual arc for a building that went from private extravagance, to bankruptcy auction, to classified wartime infrastructure, to public landmark, all within about 30 years.
