you have to narrow your possibilities a bit as other say its a big country. BC is an area of mountains, ocean and a mountain bike/ski/board paradise. The largest city there is Vancouver. see
http://www.hellobc.com The area of Whistler seems to have a lot of Aussies there and a popular spot for your countrymen to visit.
Cars here are probably same as Oz... GM, Fords, Mazdas, Toyotas lots of SUVs and pick up trucks especially in rural areas. Smart cars and hybrids more popular in big cities. \
Climate varies more than australia, generally west coast is mild summers, mild winters and the rest of the country has quite cold winters and hot summers.
