Can I claim "Flight Delay Insurance" if my flight got cancelled and rebooked?

Hi everyone,

My flight from Seattle to Ottawa via Toronto was cancelled due to weather in Toronto, and Air Canada rebooked me on a new flight departing in about 20 hours from the original departure time. The ticket was fully charged to my Aeroplan Reserve Card.

When I reviewed the certificate of insurance, I found that "Flight Delay Insurance" only states "delay" and does not address cancellation. May I ask if my situation is still eligible for compensation?

I already contacted Amex Canada, and they suggested me to contact Global Excel. However, Global Excel does not answer phone calls on weekends.

Thanks.
