First they do not give u access to the buisiness club/lounge.
They said I have to go to the United building to get access to the lounge there which was very far to go to, so ur gate is in a different building than the lounge you r allowed to go to.
Now the chair is narrow, your legs are stuck to the front seat same as in economy. My chair was number 01 and my leg was stuck onto the front wall all the flight( I am just 5:8”)
I have travelled many times business but this one in Air Canada was the worst. Air hosts were nice though.
