You may not have noticed (and since I noticed from your post that you're away) that there's a typo in the last panel, Mycroft says "Can I can you back later?" when the second "can" should be "call".
Just a little nitpick that you don't have to do anything about.
I've read your comic the whole way through and like how it's progressing, though if I'd done something like this I'd have written myself into a corner by now...
I, too, live in Canada and enjoy seeing a webcomic by a similarily-situated cartoonist (I'm not, by the way), I live on the "Other Coast" (aka, the West/Wet Coast) and also attend a university, though I attend one of the smaller campuses instead of the main campus (read: too big, poorly laid out and even more poorly documented).
