I happend to drive my family and relatives there for their exam for a few time.
Please check the attached map for the usual route of the G(G2 exit) exam.
The staff from the exam center may alter the route so if you are unlucky, you may get a different one.
I put some red dots with straight lines between them to indicate the first part of exam.
The exam center is located in the back of a shopping mall.
It's better to back in your vehicle so you can start your road test head first.
1st dot is the exam center.
2nd one is the exit from the shopping mall's parking lot. There's no stop sign but you have to make full stop as you leaving from private road to public one.
3rd one has a stop sign. After you made a left turn, you have to gain your speed to 70 KM.
4th one is a traffic light and it'll be sharp left turn so please slow down before doing any thing.
Then you will make a few pretended "changing line" and you may need to pay attention to a railway cross.
5th red dot has a stop sign and you will make a left turn then with speed limit of 50 KM and one more railway.
6th one is to curve right.
7th is a stop sign and you need to turn left again!
After you reached 8th, you will be on your own.
Usually, you will go straight and turn right when you meet the first traffic light, get on the bridge and go to the other part of Smith Fall or maybe you will simply turn left from any point beyond 8th dot.
That's all I can tell and good luck to your exam.
