According to the processing times given by CCIC, it can take up to 12 months to sponsor a spouse in Canada.

To sponsor your spouse in Canada, the sponsor must be a Canadian citizen or a permanent resident, at least 18 years of age, and must not fall within any of the ineligibility provisions. (must not be inadmissible)

You may be eligible to sponsor your spouse, dependent child, common-law, conjugal partner, parents, grandparents, adopted child, and an orphaned brother, sister, nephew, niece or grandchild. You may be able to sponsor one relative, related by blood or adoption, of any age; if you meet the conditions listed by CCIC and don't have a living relative (listed above), you could sponsor instead.
