Canada has mechanisms in place to report income to other countries, primarily through international agreements and reporting obligations. Here's a breakdown of how this works:

Foreign Income Reporting

Canadian residents are required to report all sources of income, including foreign income. This is part of Canada's tax compliance system, which aims to ensure that individuals report their worldwide income accurately. To facilitate this, Canadian taxpayers who own specified foreign property with a total cost of more than $100,000 must file a Foreign Income Verification Statement, known as Form T1135[1][2]. This form helps the Canada Revenue Agency (CRA) verify compliance with tax laws and target international tax evasion and aggressive tax avoidance[2].

Country-by-Country Reporting

Canada participates in the OECD's Base Erosion and Profit Shifting (BEPS) initiative, which includes Country-by-Country (CbC) reporting. This requires multinational enterprises (MNEs) to report financial information for each jurisdiction in which they operate. The CRA uses this information to assess transfer pricing risks and other BEPS-related risks, but not to make reassessments of income on its own[3].

International Agreements

Canada has agreements with various countries to avoid double taxation and prevent fiscal evasion. These agreements often include provisions for the exchange of tax information, which means that Canada can share income information with other countries to ensure compliance with international tax laws[6].

Overall, while Canada does not automatically report all income to other countries, it has systems in place to ensure that foreign income is reported and that information is shared with other jurisdictions as necessary to maintain tax compliance and prevent evasion.
