The 1970 Canada hurricane was an unnamed tropical cyclone that brought impact to Bermuda and Newfoundland. The fourth hurricane and ninth tropical storm of the annual hurricane season, this system developed northeast of the Bahamas as a subtropical depression on October 12. While tracking northeastward, the system intensified, becoming a subtropical storm on the following day. The subtropical storm transitioned into a tropical cyclone on October 16, and strengthened into a hurricane about twelve hours later. The hurricane later bypassed Bermuda, before further intensifying into a Category 2 hurricane on the Saffir–Simpson hurricane wind scale. Thereafter, the hurricane accelerated rapidly northeastward, and made landfall on the Avalon Peninsula of Newfoundland as a Category 1 hurricane. It transitioned into an extratropical cyclone early on October 17.
The system produced tropical storm force winds on Bermuda, which caused the suspension of schools, transportation, and interrupted businesses, although minimal structural damage occurred. Light rainfall was also reported on the island. Hurricane-force winds were observed throughout Newfoundland, which caused damage to structures, though mostly limited to broken windows. Rough seas damaged fishing dories and a fishing ramp on the Atlantic coast of the island. The cost of damage on the Burin Peninsula was estimated to be in the thousands of dollars, although the specific figure in unknown. Heavy rainfall was also reported in the region, with precipitation in Quebec reaching nearly 5 inches (130 mm). On the French Territory of Saint Pierre and Miquelon, several buildings and houses lost their roof due to strong winds.
