As part of the SFOC process you need to be aware of the airspace you are flying in and depending on the classification you may be required to file a NOTAM.
A Notice to Airmen (NOTAM or NoTAM) is a notice filed with an aviation authority to alert aircraft pilots of potential hazards along a flight route or at a location that could affect the safety of the flight.
If you don’t have an aviation chart on hand for your area, a great online resource is SkyVector: http://skyvector.com/
For checking for NOTAMs in your area, the official source in Canada is NAV Canada: https://flightplanning.navcanada.ca
Another great more interactive visual resource for NOTAMs is Zulu for Pilots: http://www.zuluforpilots.com/Map
To determine the Lat/Long for a given location, which you will need to include in the NOTAM request, you can use iTouchMap.com: http://itouchmap.com/latlong.html
