Acclimatize - You have been away from home for a while now and have been living the life of a Canadian, take a moment to settle back into life at home. You will get the post camp blues I am afraid but keep in contact with your camp friends and you will be fine.
Family and friends - Speak to family and friends and let them know you missed them and are coming home, get some plans together for when you are home.
Try something new - There are many different places to try in a Canadian airport, have fun one last time Canadian style
Stay hydrated- One of the most important things when travelling is to stay hydrated, most airports have a water fountain for you to use.
Relax - You have had a busy summer, download some tv shows and movies and sit back on your way home.
