June 30 (Reuters) - Canada's WestJet Airlines said on

Sunday that it had canceled an additional 410 overnight, for a

total of more than 800 flights, as the Aircraft Mechanics

Fraternal Association (AMFA) enters its third day of a strike.

WestJet, owned by Onex Corp ( ONEXF ) said that along with

the cancellations, it is parking additional aircraft as it

reduces its fleet to approximately 32 active tails.
