Statistics Canada stopped collecting data on divorce rates after 2008. I have, however, been able to obtain data for the period 1985-2008. 
The files are in different formats: some can be downloaded through ESTAT, some are in Excel format and the remaining are in PDF format. 

1. 2004-2005: Data for these years is available through E-Stat 
2. 2006-2008: Data in Excel files
101-6501	Divorces and crude divorce rates, Canada, provinces and territories, 2006 to 2008
101-6502	Mean age and median age at divorce and at marriage, by sex, Canada, provinces and territories, 2006 to 2008
101-6506	Divorces by age of husband and wife at marriage, opposite-sex marriages, Canada, 2006 to 2008

The rest are in PDF format. One with PDF files for the period 1994-2003 and the other for the period 1987-1993. The document for 1987 also has data for
1985 and 1986.
