This may be a bit left field, and it's quite likely that not many out of Canada will have heard of him, but listening to Eon Sinclair of Bedouin Soundtrack on the track "Criminal"... the guy's pretty damned amazing.
Also, more Canadian bias (and yes, I do also like Geddy Lee), Arif Mirabdolbaghi of Protest the Hero is ridiculously energetic, and very technically skilled. I was in music class in grade nine with the guy (like, five or six years ago), and remember him playing Jaco Pastorius all the time.
