Looks like Start.ca availability tool now redirects to Koodo - I guess Telus's plan is to rebrand Start to Koodo.
Plans look a little different - 300/30 no longer there, but they have 500/30 at $100/month which is $5 more.
With Start essentially defunct, and no fiber anytime soon here I may just sign a contract with Rogers and get 1.5gb for less than half what I pay now.
