No, it's a 1/2 since Monty eliminated one of the options. Staying with the current door is still a 1/3 chance, since, you made that choice before you had additional context, but switching doors there gives you a 1/2 chance of getting the car.
I know it doesn't make sense on paper but people have actually done extended Monty Hall tests IRL and that's the way it came out.
