How to apply for a "Nexus Card" in Canada?

The Canadian Border Service Agency (CBSA) said that the Nexus card was first introduced in 2002, which is suitable for Canadian and American citizens crossing the border by land, and was expanded to be used at airports in 2004. In 2003, eligible domestic and American permanent residents can also apply for this card. According to CBSA, Canadian immigrants need to live in the local area continuously for at least six months every year before applying. Many immigrants who are eligible to apply for the Nexus card said that they did not know that they could apply for the card, thinking that they needed to be Canadian citizens to apply.
