Sorry, but Air Transat is the biggest charter airline in Canada, not Canada3000.
Both airlines fly around 3.5 million pax. a year, but a great deal of Canada3000's flights are scheduled. Let's just say both companies don't exactly aim the same market, Air Transat being totally a vacation airline.
Just an example, Air Transat has 18 widebodies out of 23 aircrafts with the first 310 coming in, hardly suitable for domestic schedule service.
On the other hand, Canada3000 only has 4 widebodies (330s) out of 15 aircrafts but its fleet is suitable for domestic flights.
There are the facts.
