Pretty much most big routes gone until the end of April. Many to Europe gone all summer.
Thanks for posting that, but not sure what you are referring to when you say most of the "big" routes are gone. Based on the revisions posted, most of what I would call "big" routes have not been affected, although there may be fewer daily or weekly flights due to reduced demand.
The big routes between the major airports, such as Vancouver, Calgary, Toronto, Montreal and Halifax are mostly all still there. The list is only for those routes that have been affected. If the route is not
listed, it still exists. Domestically, it is the short hops and more local airport routes that have been suspended until the end of April. Obviously a severe temporary cut-back on trans-Atlantic, trans-Pacific and Caribbean routes. Many of those countries have closed their air space or barred non-resident travel. Major routes to the US, such as Vancouver or Toronto to LA or Toronto to NYC are still there.
