I must say, I think my experience with this Drive Test Centre was the same as Annie's... and based on her description of the examiner she had, I suspect we even had the same lady!
I went to this location for my entire licence (G1 through to G) and never had an issue with anyone or any process (save for the fact that I never seem to have enough ID to prove who I actually am!).
I also looked up the test routes online and practised them. I found this site to be helpful for maps:

There was one route that I didn't like, the Hwy 2 route, which takes Hwy 2 to Lawson Road, down and around the streets and then back onto Hwy 2. I remember the first time I tried it; I was coming around the ramp to get back onto Hwy 2 and BAM there's stop sign right smack at the end of the ramp!
I remember thinking, 'Who's bright idea was it to put a stop sign there??? How am I expected to merge at 80kms from a dead stop? @$#%!!!..' *sigh*
Good thing I practised that route a lot because, yup, you guessed it, that's the route I was instructed to take for my G licence!
I was tested on nearly everything. Parallel parking, emergency stop, 3-point turn, lane change lane change lane change, etc.. The only thing I didn't have to do was reverse park, but that might have been because I backed into my spot when I first got there.
Overall, a good experience and I would highly recommend this location for testing. It's true the examiners are a serious bunch of folks... but so they should be!
