I don't know why this place has bad reviews.
The food is decent. It's all pre-made ingredients at the back and when you order they assemble your pho and you get your food quickly!
I personally enjoy P4 - chicken pho with breast meat. I usually ask for the satay sauce on the side since it's nice and spicy.
I also like the chicken rice roll, but I wish there was a chicken spring roll instead. The menu is a little limited for a pho place.
The place is clean. The staff are fast and very sweet.
The downfall - it seems all of Ajax comes here when they're sick. There's always someone coughing or blowing their nose. That being said, there are always families here with children and they seem fine. I usually sit far away from the sick people and I wipe the utensils before using them.
