i am glad others were so helpful to you....

there is a paid plaza premium lounge that you can use and has shower facilities...http://www.plaza-asia.com/index.php/locations/toronto


it will actually be adjacent to the crappy KLM lounge that Cathay uses, however, depending on how early you are, you actually might be able to get into the BA lounge although they are the worst when it comes to applying the COT OW rules....so in theory you should be able to get into the small F lounge BA has...again, in the same area the plaza lounge is in....but they might say "computer says no"...to you....

i recall the BA lounge closes around 20:00 or so...

i assume from your question you are likely taking the 01:35 YYZ-HKG flight?

the plaza lounge will be open to 22:00 although it would appear it may be open to 01:30 now....this is new to me....i suspect this is because of CX's extra flights...

please post if you are allowed into the BA lounge....
