Not sure if this is a repost, just trying to help my fellow locals.
I found a store in Mississauga that regularly stocks TRINITY 10,15,and 20 wt shock oil (silicone oil) for $5 a bottle. The place is called "Galaxy Hobby and Gifts", it specializes in high end R/C cars but has a wide variety of products, including a large assortment of Tamiya/Ultra Deans connectors.
It's located in the same plaza as the T&T Asian Foodmarket, one light south of the Burhamthorpe and Mavis intersection. From a simple google search I found this information:
Galaxy Hobby & Gift
2-723 Central Pkwy W ON
Telephone : 905-848-3368

I hope this helps out other Oakville/Mississauga players looking to do some regular pre-season maintenance.
Cheers,
