Shaw Installation

Hi, Currently with Telus for Int,Phone,TV but moving to Shaw in the coming days. My installation appointment is already booked. I have some concerns because I want to keep my home phone number from Telus. Telus sent me an email saying they will cancel my services on the morning of 18th. My Shaw appointment is for 18th in the Evening. Does that mean I will lose my phone number because the line won't be active? I guess I won't have internet during the day either? thanks.
