What is Cytospora canker? Cytospora canker is one of the most common fungal diseases of Colorado blue spruce. This disease can also affect Norway spruce (and less frequently other spruces) as well as Douglas-fir and balsam fir. Trees that are 15 years old or older and are at least 20 feet high most typically show symptoms of this disease.
Canada has been an independent country since 1931, and does not belong to the United Kingdom. But it is still a member of the British Commonwealth, also called the Commonwealth of Nations, which is made up of the United Kingdom and several countries that used to be part of the British Empire.anada has been an independent country since 1931, and does not belong to the United Kingdom.

Canada formulated as an independent nation state in 1867. Prior to that, it was comprised as a series of colonies of Great Britain. Great Britain abolished slavery in 1833. This took effect in Great Britain and its colonies in 1834, effectively covering the entire British Empire. So there was slavery in what would become Canada prior to 1834, but officially there was never slavery in Canada as an independent nation. I hope this answers the question.
