Thought I'd watch this from sidelines but debate not ending
...maybe this would help:
Sponsor
130. (1) Subject to subsections (2) and (3), a sponsor, for the purpose of sponsoring a foreign national who makes an application for a permanent resident visa as a member of the family class or an application to remain in Canada as a member of the spouse or common-law partner in Canada class under subsection 13(1) of the Act, must be a Canadian citizen or permanent resident who
(a) is at least 18 years of age;
(b) resides in Canada; and
(c) has filed a sponsorship application in respect of a member of the family class or the spouse or common-law partner in Canada class in accordance with section 10.
Marginal note:Sponsor not residing in Canada
(2) A sponsor who is a Canadian citizen and does not reside in Canada may sponsor a foreign national who makes an application referred to in subsection (1) and is the sponsor's spouse, common-law partner, conjugal partner or dependent child who has no dependent children, if the sponsor will reside in Canada when the foreign national becomes a permanent resident.
Coming from some angle of expertise...for sure this is an additional complication however if one can show clear ties to Canada, there shouldn't be any trouble...ties such as a job to get back to, family in Canada and future plans in Canada. You can show through communication that the couple were having a hard time apart and after much consideration decided upon this. But I think it would be key to show you will come back to Canada immediately after your spouse becoming a PR and more importantly have something to get back to such a job and family or your house in Canada etc. Also remember you must be able to support your spouse so if no job when back...how will you survive? Remember under the context of Canadian culture maybe its not normal to say our family will support us.
My two cents...
