When can I ask for a divorce?
As soon as one of the following three circumstances has occurred:
the other spouse has committed adultery, the other spouse has committed cruelty, or the spouses have separated.
As soon as one of these circumstances has occurred, a spouse can commence an application for divorce.
If separation is used as the ground to obtain a divorce, the spouses need to have been separated for at least one year before a judge will grant a divorce judgment.
What is an uncontested divorce?
When the spouses have signed a separation agreement that has resolved all issues such as custody, access, support and property division, and they now both want to be divorced, then one of the spouses can commence a petition for divorce that consists of a request for a divorce only. One spouse has it served on the other spouse. If the other spouse agrees to a divorce, then he or she may choose not to contest the petition for divorce. That is why it is called an uncontested divorce.
How long does it take to get a divorce?
An uncontested divorce usually takes between eight to 16 weeks. A petition for divorce that is contested usually takes much longer. There are many factors that affect the length of time it takes to get divorced. Unless the reason for the divorce is adultery or cruelty, the spouses must have lived separate and apart for at least one year.

There is a requirement that one party is resident in the province you are filing for divorce in for a period of 1 year to initiate divorce proceedings.

The actual requirements (proof of adultery, filing requirements etc) will depend on the province you live in.

I do wonder what the hurry is though - and how long you (or your wife) has had their PR status for!
