Multi airline flight ticket

daren1961

I have a flight booked from Leeds Bradford to Toronto (return) on a multi airline ticket booked with Lastminute.com departing on July 30th 2020, returning on August 3rd 2020. The flights are with BA & Air Canada (connection at Heathrow). BA recently announced that they have pulled out of Leeds Bradford and all flights are cancelled. Does this mean that the whole ticket is now cancelled? Due the coronavirus the UK government (FCO) are saying essential travel only and Canada are not permitting tourists for the foreseeable future, not to mention the 14 day quarantine periods in both countries meaning a five day trip actually now require 33 days leave!.

I have tried to contact Lastminute.com but to no avail yet.
