Short answer yes it is possible. Since you are in Canada, it needs to be 15 years or older.
However if you are in Quebec, then you cannot register a RHD vehicle in that province. If you are elsewhere you should be okay, but hurry up because B.C. is looking into closing that door too.
We did just that. We flew to Sydney, bought a pop-top HJ75 and drove it all over the world for years then sold it to a friend in Belgium. It just got sold to Greg Miller for his Land Cruiser museum in Salt Lake City. I think it is getting here like this week. I thought about buying it back, but did not for 2 reasons - I want a LHD because of Central America restrictions, and I want the 1HZ engine. Even though I had almost zero problem with the 2H, it is a very old engine by now, even by African standards.
Budget about $15K to $40K for the truck, then another $5K for shipping and you should be in the right ball park.
However one last piece of advice...these are slow trucks. If you are looking for something for North America, I don't think it would be my first choice. They are extremely reliable, but you're not going to have much fun crossing the Rockies in the slow lane or trying to keep up with traffic on Highway 5 on your way to Baja. My friends have one in South America right now (

But if you are looking to go explore Africa, then there is no better choice.
