Both Valvoline VR-1 & Joe Gibbs are great oils. Whatever you can afford (or justify). :dunno:
Alternatively, RP Oil in Whitby (close to you) sells Brad Penn Oil which is another great oil. It may be less expensive than the others. Think I paid just over $65. for a case of 12 US quarts last time I purchased some. I'm sure it's available in a multitude of viscosity / grades...10W-30, 10w-40 or 20W-50.
Just finished the Oil Change and it seems my car no longer is leaking. But that is yet to be confirmed. I'm pretty happy with the VR1 so far very smooth running. I think the leak might have been the previous owner not completely tightening the oil filter down. Keeping my fingers crossed.
