Now on Optik cabling

Where I live 250 is the lowest fibre plan directly advertised on Telus' website currently, and 3gbps is the fastest plan offered. You can still get slower speed plans but you would likely have to call in to get them. I do know that 15/15 is the lowest speed that is currently available on fibre but it's just not advertised.

The billing will still be based on the plan that you are subscribed to on paper, not the speed you are getting over top of the plan. Before your contract is up, check Telus's website or call in and see what the pricing options are at the time. If you're on a two year contract currently with a reduced rate, after the contract is up you would go up to the regular price if a new contract isn't put in place. You should be able to start a new contract before the current one is done.
