depends upon what you mean attacked.
During the War of 1812 Canada was attacked by American forces on numerous occasions, most notably in the Niagra area. Check out the site http://www.archives.gov.on.ca/ENGLISH/exhibits/1812/index.HTML
also see http://www.archives.gov.on.ca/ENGLISH/exhibits/1812/places.htm for an interesting list of important places from the war. This link will give you an idea of how many places were actually attacked by the American troops.
In 1866 Canada was subject to attacks during the Fenian Raids http://www.townshipsheritage.com/Eng/Hist/Military/fenian.HTML
During WW2, in 1942, German U boats sailed up the St. Lawrence river 6 times (approx 300 km from Quebec City) and managed to sink, in Canadian waters, 3 warships, 20 convoy ships, and the first US troopship sunk during the war. U boats returned to Canadian waters to sink 2 more ships. (http://www.acc-vac.gc.ca/remembers/sub.cfm?source=history/secondwar/battlegulf/uboat)
In June 1942 a Japanese sub shelled a lighthouse on the Vancouver coast.
Between 1944 and 1945 the Japanese released over 9000 fire balloons on a rather bizarre attack on North America. The balloons were caught up in the jet stream and managed to make it to North America. Recently released reports show that some of the balloons made it as far as Saskachewan.
Not sure about any other attacks. If I find our more info I'll post it.
