Full time in my travel trailer, Challenge No. 1: Internet

I am planning to live full time in my TT this summer and have identified a number of challenges but the one that has me stumped is how to get reliable secure internet access. I work online so this is a priority.

Any Canadians living full-time in a seasonal, permanent location with advice?

For example, if I have a permanent location is it possible to get service from a rural broadband provider like xplorenet?

As of now, the only option I can identify is to tether my laptop to my cellphone, which could get very expensive.

Thanks!
