So just looked into internet from Telus:
Optik High Speed Turbo is 25Mbps download speed, no listed upload speed, 500GB/month data. $44/month (This is Telus's best internet option available)
Shaw High Speed 20 is 20Mbps download, 0.5 Mbps upload, 200GB/month data. $55/month (This is Shaw's second lowest internet option available)
So if you are a low-end internet user Telus may be right for you. However for those that plan on streaming HD through Netflix, download/upload torrents, and are generally heavy internet users you have no other option than to go with Shaw.
Shaw offers 50Mbps, 100Mbps, and 250Mbps connection with up to 15Mbps upload, and unlimited data. Telus can't compare.
