It is not a busy month in terms of numbers, far from it.
May is just before June-July, their quota resets on the 1st of July, so May is the month where they are busy finalising older applications so that they can meet their quotas.
Then they go on vacations.
the majority of Canadians go on vacation in the best months of summer and leave work behind for 2 or 3 weeks. then these officers come back to find a pile of applications from may, june and july, and guess what they do? doesn't take a scientist to figure out that they start working on this pile from top to bottom, and May is at the bottom.
look at the figures from Trakitt.com, up till May there is a ton of activity especially Medical requests up to 30 per month. After May medical requests is 3 or 4 per month. Why is that? they met their quota.
May- early June applicants might as well have applied in December-January next year.
People are dying in our countries today, don't think that CIC has invented justice and equality, it is a flawed system like most man made systems.
