Today's Charlottetown Airport maintains a remnant of the airfield's runways near its general aviation terminal, but all buildings and most infrastructure have been removed.

The municipal and provincial governments divided the cost of developing the new airport in exchange for an equivalent division of revenue sharing.

In preparation for military use, the airfield underwent significant expansion with the main access point being changed to Norwood/Union Road.

Three paved runways were constructed in the classic BCATP "triangle" configuration, along with various buildings and support facilities.

Three runways were listed as follows:[1] Whereas the Royal Canadian Air Force was operating its airfield at RCAF Station Summerside and another further to the west at RCAF Station Mount Pleasant, the Charlottetown airfield was to be controlled by the Royal Air Force (RAF).

RAF schools in Canada during the war were extensions of the British Commonwealth Training Plan until they were officially incorporated into the BCATP in 1942.

Along with RCAF Station Summerside, the Charlottetown airfield also supported various patrol operations by the RCAF's Eastern Command, including coastal patrol aircraft dedicated to hunting German U-boats which were operating in the Gulf of St. Lawrence and St. Lawrence River during the 1942 - 1944 period.
