Canada has implemented the web-based travel verification systems for the VISA exempt for the foreign national which is known like the eTA (Electronic Travel authorization). The implementation of the program is only one of many initiatives which Canadian government is working for as part of the joint agreement with US to better protect the border they are sharing.
The US and Canada have embraced the policy designed for improving the security of borders they are sharing as well as additional collaboration that includes sharing of the visa and the immigration information they can gather. An enforcement of eTA is the Canada’s initiative in response to their agreement. The citizens of the required countries are needed to obtain Canada eTA before they fly to Canada
