1) First city is Toronto,there are 5 429 524 inhabitants, it situated in Ontario province which is in the south. Next city is Montreal, which is located easter of Toronto, in Quebec. Population there is 3 519 595 inhabitants. And the third city is Vancouver. It has 2 268 823 residents. The city is located in British Columbia on the west coast of the country.
2)By far most valuable natural resource in Canada is petroleum. Canada has the third largest oil reserves in the world after Venezuela and Saudi Arabia. The second most valuable resource probably is farmland. Canada has vast amounts of agricultural land on the Canadian prairies. Most of this production is exported to other countries. It also has large amount of gold, silver, diamonds, copper, uranium and other minerals. It is not surprising considering it is the second largest country on the Earth after Russia.
3)I'd like to visit Toronto because it has a lot of interesting places such as Royal Ontario's museum, Distillery District, which is representative of the Victorian era and architecture. Also i think I would like to visit Ripley's aquarium of Canada. There I will be able to see beautiful sea animals and visit interesting events and lectures.
