This is the first decision, and it is the one with the longest shadow. The two routes differ on appeal rights and on travel, and those differences only matter once something has gone wrong.

If the application is refused, is there a right of appeal?
In CanadaNo right of appeal. The route after a refusal is judicial review, which is a different and narrower thing.
Outside CanadaYes, a right of appeal to the Immigration Appeal Division. No appeal where the person is inadmissible for security, violating human or international rights, sanctions, serious criminality or organised criminality.
Can the sponsored partner work while the application is processed?
In CanadaYes, but when depends on status. With valid, maintained or restorable status, an open work permit can be applied for once IRCC acknowledges receipt. Out of status under the spousal public policy, only after approval in principle — see below.
Outside CanadaNot while they are outside Canada. The open work permit requires being in Canada and living with the sponsor. An applicant who obtains a visitor visa and joins the sponsor here applies on the same basis.
Can the applicant travel while it is processed?
In CanadaRisky. This class requires the applicant to be in Canada, and there is no guarantee of being allowed back in. Leaving can put the application at risk.
Outside CanadaYes — the application does not depend on the applicant being in Canada. An applicant who has come to Canada and is relying on a work permit faces the same re-entry risk.
Where can the sponsored partner live?
In CanadaIn Canada, with the sponsor.
Outside CanadaIn or outside Canada. A sponsor who is a Canadian citizen living abroad must show they will return to live in Canada.
Processing times
In CanadaCheck the current times published by IRCC. They move.
Outside CanadaCheck the current times published by IRCC. They vary by visa office.
If the partner in Canada is out of status
A spouse or common-law partner already in Canada without valid status can still be sponsored under the in-Canada class, through the spousal public policy. This is one of the most useful routes available to couples, and one of the least understood.
The trade-off is the work permit. An applicant relying on that policy cannot apply for an open work permit when the application is filed. They must wait for the approval in principle letter, which comes after the first stage of the permanent residence assessment.
Once approval in principle is granted and the applicant is still out of status, the work permit application has to be made on paper rather than online, enclosing a copy of the approval in principle letter and a letter explaining why it cannot be filed online.
That gap between filing and approval in principle is the period couples most often misjudge, and the reason the route decision is worth taking advice on before anything is submitted.
