You do not get any ZED/ID90 or standby company travel at all during the first 6 months (industry standard)
However with EK you get confirmed passes right away. They are more expensive but they are confirmed which you'll need around Christmas.
Toronto service starts in the fall, and you can buy a cheap ticket on WestJet or one of them low fare carrier to Vancouver.
I'm not cabin crew so can't tell you how to work your days off for that.
Good luck
