Is this possible? Yes.
Is it likely? No.
First thing to try is visit fast.com or speedtest.net with a web browser, and check your speed. Whatever result you get, compared it to your Shaw or Telus bill to see what speed you are paying for (usually phrased as "Internet 100," meaning 100Mbps, or some other number. If there's a big discrepancy between your results and the internet speed you're signed up for, you may need to touch base with your provider. If you're using a third-party router, that could also be the issue.
