Acanac counts on you knowing what you're doing
My install was seamless, I only needed the tech to come out to flag the line as TPIA. They did however knock on my door to ask if I was getting connected, but that was it.
When I first signed up, it was possible to have more than one connection active on a line at a time, however I believe Rogers has stopped allowing this. Your cancellation date must be on or before you new sign up date.
