Sagitarious is still in the southern hemisphere, we aren't going to see it until at least June (August is the best time).
Also you'll need to get away from the city to avoid the light pollution.. I usually have to drive at least an hour north of Barrie to find complete darkness.
If you get far enough away from the city with zero light pollution you'll want to look north and try to find Cygnus, that's the only part of the Milky Way that might be visible at this time of year, it will be right above the horizon and not high in the sky.
Here is a great free program I use to figure out what's going to be where, when
