Welcome aboard Saif. As you can tell from Harry's Google search link, there are many hobby stores in Toronto. Some are specifically geared towards remote control, while others have more of a kit focus. Even amongst the shops that specialize in kits, some have more of an automotive selection than others. It depends on where you live as well. Some of the shops I like:
Wheels and Wings Hobbies - Danforth near Woodbine (east central) * good car selection
Hornet Hobbies - O'Connor south of Eglinton (east central) * improving car selection
Hobby King - Highway 7 east of Woodbine area (east north) limited car selection
Dragon Hobby - Gerrard east of Broadview (central) good car selection
Panther Hobbies & Trains - Dundas west of Highway 427 area (west central) good car selection
Dailey Hobbies - Thickson north of Dundas St E (Whitby) good car selection. There are many more shops in the GTA.
My two favourites are are marked with an asterisk. Hope this helps.
