I grew up in Manitoba. It's pretty much all flat prairie/lakes/tundra. Just by a quick google-maps it looks like your hills in Tennessee are better. If you want to jib some park then it might be ok. Within Winnipeg there isn't much, I know of one place called Spring Hill. Outside Winnipeg the better place is probably Assesippi (4hrs NW)
One thing I can't stress enough is to make sure you bring lots of warm clothing. Manitoba arguably is the coldest place in southern Canada so don't be surprised if it's extremely cold (I've seen temps in the -50s there) Have fun!
