Effective immediately, you are allowed to "sponsor" your spouse - defined to include your married partner, someone you have been living with for two years (a common law partner), or someone you are unable to live with because of the laws or social context in your respective countries (for example, consider a Muslim from Iran who is in a relationship with a Canadian: the two cannot live together as spouses in Iran; and Canada may deny a visitor visa).
But now, says Canada, there are two new requirements. According to Jason Kenney, these new requirements are designed to stem fraud arsing out of fraudulent relationships in which a couple marries solely for the purpose of bringing the non-Canadian to Canada, sometimes for a fee.
The first requirement relates to you only if when you made your application for spousal sponsorship, you had NOT been living together for two years AND you have no children. In that situation, the law now requires that you live together for two years after you come to Canada. The rule makes an exception if you are in an abusive relationship. In that case, you should go immediately to your doctor, and report the abuse so it is on record. Then you should go to a lawyer, or call Immigration Canada, and explain why you have moved out.
The second requirement is that once you are yourself sponsored as a spouse, you cannot sponsor anyone else as your spouse till five years have passed from the date you acquired permanent residency.
