The Royal Opera House Covent Garden has started posting very high quality full length opera and ballet videos on its Youtube channel.  So far there’s the 2012 production of Britten’s Gloriana, a 2010 Così fan tutte which, as far as I can tell, is not available on DVD and Handel’s Acis and Galatea directed and choreographed by Wayne McGregor which is definitely worth a look.  There’s also several ballet productions.

Oper Frankfurt has also been posting Lieder recitals “zu Hause” though so far none of their contingent of Canadians has featured.
