Out of province student buying a car in province of study

I'm from BC and living in Ottawa for my master's degree, because I'm a student I haven't needed to change my licence over. I'm moving apartments in 2 weeks and plan on switching my licence with the new address. I am going to look at a car soon and I know it would be simpler once I have an Ontario licence to buy it then, but it would helpful during the move to have the vehicle. Can I get temporary registration until I apply for my Ontario licence in a few weeks? This will be my first time buying a car so i don't fully understand how the administrative process works.
