在加拿大跟一个拥有加拿大国籍的人结婚后，自己是成为公民还是移民？

这要看你本身在加拿大是什么身份？

比如，你是留学生。
你与加国公民结婚，而且被移民局认可婚姻，则你即时拥有加国‘永久居留权’，拿“枫叶卡”，是加拿大永久居民。
如果，你在加拿大本身就已经是“永久居民”，你结婚与否，身份都不会有提升。仍然要住满一定年限，并通过移民局的“归化考试”，考加国历史、地理、一些简单的法规，以证明你融入了加拿大社会，可以合格地成为加拿大公民。
这些考试并不困难，但关键是它用英语或者法语考，许多大陆移民不谙英文，被拦在此外。但是加国永久居民与公民的身份，其实区别不大。甚至出国都持加拿大护照（内容有注明而已）。只是永久居民无法参与加国政治事务，简单说，不可以出任公职（即便是市政施工人员也不行），不得投票选举。如果你不关心政治，基本上问题不大。但是，回 存在一定风险，国内当局会以你仍然是 公民为由，限制你再次出境（由其是你在国内身涉一些棘手的麻烦事时）

其实大家都搞的太复杂了，你在加拿大结婚后，你不是加拿大移民也不是加拿大公民，经申请后可成为加拿大移民，再住够时间经申请后可成公民！

是可以拥有枫叶卡的移民，不是加拿大公民

你现在在哪呀?如果在加拿大的话,这东西就不用拿出来问了.如果不在加拿大的话,就先让那个加拿大公民回来跟你办结婚证吧.领了结婚证后,再由那个加拿大公民担保申请你移民

那要看你有没有加拿大的国籍,跟他没有关系.

先移民，满一定年限后申请成为公民

All above me is wrong.

You said if you get married in Canada, so I will assume you will be in Canada with a visitor's visa.

To answer your question:

1. If you are married, your visitor's visa will not change. You will not become a landed immigrant or a citizen automatically.

2. Your spouse must submit a sponsorship and you submit an application for landed status. In fact, the 2 applications are combined to 1. Before status granted, you cannot leave Canada.

3. After your application for landed status is successful, you will be issued a permanent residence card. You have to continue to meet the qualification by staying in Canada for 730 days in every 5 year. You still belong to Chinese citizenship and hold a Chinese passport. You don't have access to a Canadian passport. You can find a job except federal government job. You can vote, except federal government election. You have the right to remain in Canada and use your Chinese passport to travel. If you commit a serious crime, you will be deported though.

4. After residing in Canada as a landed immigrant for 3 years, you can apply for Canadian citizenship by passing a written examination. After that, you become a Canadian citizen and can obtain a Canadian passport. China does not allow dual citizenship, so you have to surrender your Chinese passport, and every time you return to China, you need to apply for a visitor's visa, because the Chinese government sees you as a foreigner.
