need help to choose a tree
 

Hi,
I am living in Albert, Canada.
I paln to plant some trees in my back yard close to my fenc. My home is
about 10-16 ft far from the fence. I like to have a tree that can block
my neighbourhood view in my back yard very well. In another words, I
like to have a tree that spreads widely. However, I don't want the
tree's roots give me trouble by intruding into my basement walls. Can
you please help me in choosing a right tree that can survive canadian
cold weather?

thanks
