The EN to the regulator should work as well, but since that will shut off power to the GPS you should make sure to set any IO pins that are outputs to the GPS to tri-state (ie inputs), or drive them...
I was checking the manual but at the same time the pcb board, which is an adafruit ultimate GPS. They do have an ENABLE pin but this is not coming from the GPS module but from the mic5225 3.3V...
Both of those have an NRESET input which is a low-active signal that will reset the module.
Connect that to one of the pic's IO pins (as long as you're powering the pic at 3.3V).

Re: GPS Project: PIC18F26K22 or PIC18F46K22
What i did, is to have all ports low, until the LCD is powered up. Then i set one of the PIC's port to high to enable the GPS's regulator.
