Shit, you got a better deal than me haha but maybe that's because you also got TV (I just did internet).
The work I had to do inside myself was extremely simple, they fished the fiber into my basement and I just had to get on a ladder and pull it through. Then I had to snap a connector on the end of it, clean it with an alcohol swab, and plug it into the modem (DO NOT look into the fiber if they turn it on before it's plugged into the terminal). If you need a router I think they give you one too, but most people I imagine are using their own router, so all you will need to do is unplug the ethernet cable from your Shaw modem and plug it into the Telus terminal and you're up and running. There was zero wait time to "activate" or anything, it just worked instantly as if nothing had ever been changed, except my speeds were way better and my ping was 8 times lower.
I hope it all goes smoothly for you, let us know how it is
