Narrative:

Normal push back and salute from guidance in vancouver. First officer (first officer) called for taxi with ground control. We received taxi instructions to runway 26L. Instructions were to use the ramp side taxi out for our initial directions. After clearing left and right I began spooling up for taxi. First officer looked right again and stated 'wait a minute!' another airplane was coming from behind; at a fast taxi speed and using the bypass ramp area. Ground did not tell us about [the] aircraft. The aircraft was overtaking our aircraft at an unsafe speed and distance. The gate push area and bypass/T taxiway is a tight intersection with our aircraft and not large enough for them to overtake us. I depressed the brakes abruptly; our aircraft taxi speed was 3-5 knots. I came to a rolling stop. This caused flight attendant X to brace herself against a first class seat with her side/back; and caused flight attendant Y to brace herself with her right arm on an economy seat. Both reported to be hurt and that they would file a report. All flight attendants reported able to continue their duties and did not request medical attention.
