In the years right after the policy was introduced, Canada experienced the same type of economic boom that many other nations experienced, as well as the construction of a manufacturing base and the development of the nation, which is generally what the Tories and economic nationalists use to justify the policy. However, Canada also suffered a net population outflow, as more people emigrated from Canada (usually to the United States) than arrived as immigrants. This population overflow was initially a result of the success in the National Policy. The National Policy took a broader perspective for the Conservative party, it advanced the policy with its larger development strategies. The Canadian Pacific Railway (1880) and the Dominion Lands Act (1872) provided new immigration policies and easy transportation of immigrants.
