Obviously, clothes are a priority when packing for your international move. Yet its unlikely you'll need everything in your wardrobe.
Think of moving as an opportunity to pare your collection to clothes you actually use--donate the rest to charity, hock what you can on eBay, or toss whatever is beyond salvage. Also, keep in mind what's weather-appropriate for your relocation.
Summery clothes in colder climates, such as Quebec, will get minimal use. If you have just a few long-sleeved pieces, those might be lifesaving during surprise temperature drops certain regions experience year-round. Likewise, if you're moving somewhere warm--say Central America--you can probably stand to lose most (if not all) of your winter pieces.
Depending on where you're moving, it may be essential to pack home comforts, such as deodorant or conditioner, that you won't be able to get in your new home (as many expats do in places like Japan). However, heavy liquids add weight to your luggage, which may cost you more than the expense of replacing those toiletries in your new home.
On the same note, make sure you have medicines you might need abroad, including over-the-counter medications (Excederin, for example) that won't be available globally. Chances are good you'll find a suitable replacement in due course, but it's wise to have an emergency reserve of anything you might need in a pinch.
Family photos, DVD collections, a favorite pillow, etc. are discretionary. Chances are you'll be happier with the minimal amount of luggage possible, and you won't miss your duck-shaped shower caddy or expensive mahogany shoe rack all that much when you've reached your new home.
However, anything you use on a regular basis (a beloved cookbook, for example), will be a comfort in your new home, and is perfectly reasonable to bring along.
Once again, consider the price of additional weight with your luggage.
If you're moving somewhere with a higher currency value than your current home (for example, the United Kingdom), buy items such as umbrellas, snow boots and winter coats at home if you will need them immediately at your destination.
Sometimes it is cheaper to have these items shipped to your new address rather than bringing them on the flight.
With such a big move, less is more. Whatever you can live without, it's best to leave behind. Moving to a new country is a fresh start, and you don't want to be bogged down with clutter.
If there's anything you're unsure about, pack it up and leave it in a box with a trusted friend or family member. If you get abroad and decide you really should have brought it along, have it shipped.
Safe travels!
