[dingoatemybaby]

When you have been accepted for working visa in Canada just want to know how long you can go without using it? if i was accepted in November last year, could i not take the offer for a year or 2 or 4? just want to know how long?

The visa should usually have an enter by date on it often just 12 months or less before you need to arrive in Canada to activate it. Landing to activate it is key, what you do after that is up to you depending how long the activated permit is valid for so activate it or lose it.
