There is no legal limit how mush someone sends to another country, even Canada. There are no taxes to be paid on money you own to another country when it arrives in that country. It is not income.
The OP wants to send money he saved from work over several years back home. He can send the full amount to the UK with no issues at all. Saving less than NT$200k a year is a small amount.
If you have anything helpful to add to their post, please reply there. Your statements about limits to Canada are also incorrect. There are no limits yet you claim 10K per year, where did you get this idea from?
Over 10k is scrutinized and you need to show receipts. Bank statement from sending institution and such. It’s a profits from drugs and laundering thing. Could be @TT was being helpful, but not fully.
I see people sending funds to Canada to their children and all they do is fill out the forms and done. Some older people still go to the bank instead of doing online.
10k is the amount you can bring over in cash on airplane, and must be declared. In the USA.
But you can wire a lot more than that, used to be 90k without having to make any additional declarations, however the bank will inform the IRS if anything looks sketchy.
