Interesting dns

I have been doing a trace route to www.shaw.ca 3 times in a row and got 3 different results.

This is highly confusing to me. www.shaw.ca works fine in any web browser so it is pointing to the correct location.

 

I use 8.8.8.8 as primary and 1.1.1.1 as secondary DNS server.

 

Below are the routes. Why are they like that?
