Oh, nsweezie, I can't believe I didn't see this post before. I'm so sorry about beautiful Ebie. Please know that she will be in my thoughts and prayers.
When my Charlie (Rainbow Bridge) wasn't eating because of a sinus infection, the vet told me to feed him Sheba cat food. It's one of the strongest (yuckiest) smelling things on the market. The duck flavor smells particularly strong and he ate that without a problem. I don't know if it's available in Canada, but you might look for it. I'm glad to hear that you have been able to get her to eat and drink a little.
Hang in there.
