Mississauga and Brampton are ethnically and religiously most diversified cities of the world. Many ethnic groups practicing many different religions have made this region their home. Although I am sure all of them are patriotic Canadians first, they still stick to the roots. You will find Buddhists from Vietnam and Thailand, Coptic Christians from Egypt, Sikhs from Indian state of Punjab, Muslims of all denominations from Nigeria to Burma, and many others living side by side.
Please be cautious of the ways of the others. One behaviour that may come naturally to you may be odd for the other e.g. shaking hands with women, treating guests to food containing beef or pork, etc.
Keep a sanitizer lotion / cream handy all the time. It pays to use it everytime you get back into your car after an adventure outside. The reason is that North American soil and environment is rich and supports allergy giving plants and other insects. Also, while outdoors, we and especially children use many public facilities like water taps, washrooms, hand rails, information boards, etc. Infections can be easily transmitted. Use a sanitizer generously on hands every now and then.
Admittedly, Canada has the most beautiful seasons that we have ever found in a country. However, weather is a different story. Be adequately prepared for inclement weather in late spring, summer and early fall. You may notice that you may be sweating in the mid-day and yet freezing in the evening on a particular day. Keep a light jersey handy all the time. If you cannot carry it in your hands, carry it in the car.
Due to UV radiations all around the year, use an adequate protection when exposed to the sun.
Mosquitoes can make your life difficult in summers. A mosquito repellent is a must when spending time outdoors. Cover yourself properly in bush country and in urban parks. Avoid wearing colors that attract these pests.
Our lovely parks down by the water come with a warning (besides hold your nose in the summer the water can stink) WATCH YOUR STEP! We are over run by geese...lots of geese...so where there are geese there is geese poop!
Please don't feed the geese either, or any other birds you might see in the area.
