It is not that simple. Canada and the United States are very different countries with very different laws. In fact when it comes to opening an account with a Canadian financial institution I would not be surprised at all if a Japanese citizen or entity would have have a way less problems than a US citizen or entity. The reason, which I suspect is the same reason behind this deal, FACTA. In any event here is a list of questions I placed in another thread on the Canadian issue.
Actually for a Japanese citizen or company, it is impossible to open a bank account in Canada, except if holding a Canadian visa or creating a Canadian subsidiary, while a US company can ask its bank to have a deposit method available in Canada and route transfers to Canada domestically.
Some questions from the perspective of a Canadian MtGox customer.
1 ) What is the location of the assets held BTC and fiat held by MtGox on behalf of the customer Japan or the United States?
2 ) What is the location for tax purposes where the trades take place Japan or the United States. Furthermore which tax treaty will apply to the business relationship that between Canada and Japan or that between Canada and the United States?
3 ) Which country's privacy laws apply to personal information of the customer Japan or the United States?
4 ) Will the customer be required to change banking information for withdrawals already on file with MtGox?
5 ) Will a Canadian customer be able to continue to receive funds in US dollars into a US Dollar account with a Canadian bank?
6 ) Will the customer be required to provide an IRS form W-8?
7 ) Will withdrawal limits change as a result of this for Trusted and Verified customers?
8 ) Will there be any restrictions as a result of this for logging into MtGox by Trusted or Verified customers from outside of Canada and the United States for example while travelling?
9 ) Will USD on deposit benefit from FDIC pass through insurance?
and some more that I thought about later.
10) How will the Canadian dollar denominated MtGox accounts be impacted by this?
11) What measures if any has Coinlab to comply with Canadian financial laws and regulations. Has Coinlab completed any of the registrations required in Canada?
12) How familiar are the principals of Coinlab with Canada and its laws and regulations. Have any of them visited Canada?
13) How will Coinlab deal with the Canadian GST/HST?
14) Will Coinlab be providing service in French? This is a requirement in many parts of Canada
Welcome to Canada / Bienvenue au Canada
1) For now all BTC assets are still held by MtGox Co. Ltd. in Japan. Already explained this earlier, but basically we are waiting for CoinLab to have a deposit handling system secure enough first.
2) It depends in which country you are located (ie. on you own country's tax laws). For more details please contact an accountant or lawyer in your own country.
3) For Canadian customers who accepted CoinLab's ToS, privacy policies will be those specified in there.
4) Customer withdrawal data will be ported, however customer has the option to ask for his banking information to be removed (by contacting the support) prior to transfer.
5) Of course
6) No idea, it depends on US and CA laws. I believe CoinLab will be able to answer that.
7) It depends on US implementation of FATF rules, which I believe are mostly similar to Japan. I believe CoinLab will be able to answer that.
8 ) Shouldn't.
9) I guess it should since CoinLab is registered as MSB, however I'll let CoinLab reply to this.
10) No impact unless the holder is either Canadian or American. Canadian and american customers will see their balance in USD and CAD ported over to CoinLab upon accepting the CoinLab ToS. Any balance in other currency will have to be closed and converted to one of CAD/USD/BTC.
11~14) I'll let CoinLab reply to this.
