A flag mix-up caused Canada a bit of embarrassment today — day one of a state visit by the king and queen of Belgium, the first such visit in over 40 years. Belgian journalist Wim Dehandschutter was the one who first pointed out that the flag marking a tree Belgium's Queen Fabiola planted on the grounds of Rideau Hall back in 1977 was actually Germany's flag.

"While we were preparing for the tree planting ceremony on the grounds of Rideau Hall, it was brought to our attention that there was a mix up with a small flag," said Marie-Ève Létourneau, a spokesperson for Rideau Hall.
