Read a News Story on CBC tonight about Squirrel's eating MTS lines and the delay to have them repaired.

I think MTS may have been singled out as I'm sure Shaw has this problem as well but I found it interesting that 17% of problems are caused by squirrel's. Quite the interesting article.

There is big money in producing animal guards for the telephone, cable and electric utilities in North America.

If you are ever on South Drive in the  Wildwood park area in Winnipeg, and  look on the utility poles, you will see that  MTS has a triangular squirrel guard lashed onto  their main aerial cable on South Drive to  try and prevent this problem from happening.

Manitoba Hydro has at some of their substations and local back lane transformers special insulators with shields to prevent squirrels from taking the transformers down when they short out the line to the metal transformer body.

I am not sure if MTS has this problem in the rural areas but some of the US utilities have to use special gopher proof  underground cable as the gophers like to chew on the the underground lines.

And I should add, because Shaw had their coax over-lashed to the MTS lines before the guard was applied, the MTS squirrel guard also protects Shaw from having that problem in that section of  Wildwood park.

I wonder if damaged telephone distribution cables are more likely to have service issues compared to coax? There are many pairs inside, each with dedicated service, whereas coax distribution cable is just one signal being split off at each tap.

Also, coaxial cable only has a centre wire and a shielding wire, which might continue working sufficiently, even with some damage, compared to twisted pair.

Not sure about Shaw but I have read that the major US cable companies do have techs that go around looking for signal leaks due to cable insulation failures due to tree rubbing, squirrel's etc..
