Sisters Khadeja and Yumna Farooq say a Toronto landlord is raising their rent by $7,000 per month

Which means an initial rent of about $2500? So not doubled.

Insurers unload some of their risk by selling cat bonds, which require investors to pay damages resulting from a natural disaster, if specific conditions are met. The bonds offer fat returns, but carry the risk of total loss of principal if the worst happens.

Quite the opposite! The apocalypse will cost them a lot of money. Maybe that would incentivize them to work to avoid it, although I doubt it.
