Normally when a building is wired for fibre, it is wired to every unit. Telus installs a box above the door to each unit in the hallways, if fibre was added after the building was built. If they installed it using this method, you'll see a box like the following in the hallways above the doors to each unit:
There would typically be a little white plastic plug on the wall above the doorway inside the unit where the fibre would be pulled into the unit.
If the building is more recent, it may have been run to units through a smart telecom panel where fibre/coax/ethernet all meet.
If the building was wired up but the previous unit owner just didn't have Telus service, Telus will send out an installer and get things hooked up. If there was never a fibre run to the unit, that would be a little more complicated but the installer would need to be on site to confirm.
