The players and their families absolutely loved it . But just like swag culture it ' s not necessarily a means to an end . I wish we could have some of that hardnosed , nobullshit attitude . <| sep |> I ' ve been visiting my inlaws overseas and they gave me some cash . From what I understand , I can bring back any amount of cash but I have to declare it if it ' s over $ 10 , 000 CAD . I will declare it . You understand it perfectly . This is quite refreshing because so many people fail to understand this ! No you do not need to carry any proof with you . Once you declare it , the officer has to decide whether the funds are likely from legitimate sources or are from criminal activity . If the officers have concerns that the funds are likely to be proceeds of crime , they need substantive evidence , and you could appeal any such decision afterwards once you ' re comfy and back in Canada . Seizures of suspected proceeds of crime are uncommon and are considered a big deal . If the officers do not believe the funds are illegitimate i . e . they believe your story about inlaws , they will have you fill out form E 667 . There are dozens of people everyday at each big airport who merely need to fill out this form . If you ' re curious , you can see it online . It doesn ' t require much information . On the other hand , if you didn ' t declare the money , they can seize it regardless of whether they believe it is legitimate or illegitimate .
