For riding to work and some mountain biking I certainly wouldn't buy anything from Canadian Tire or Wal-mart. Go to an actual bike shop. I wouldn't get anything with rear suspension until going over the $1000 mark for sure. Get the lightest bike with the best components that is within your budget. You be the most satisfied with that.
