There IS NOT quota for spouse sponsorship. For parents and grandparents is 5000 per year.
I recommend you to read this article.
pacificimmigration.ca/en/news/immigration-quota-for-2013
For spouses, partners and children the upper limit is 48.500 visas worldwide in 2013. If they already hit this number Visa Offices can't issue a visa in this category during December 2013. Applicants have to wait for January 2014.
Now some people say its just a "target" but not a "quota" but with a decent knowledge of english, you will probably know it is pretty much same thing... Matter of fact they are more likely to hit the low-end target than over it.
