I have decided to try and go back to Calgary, that way if I get in I can then fulfill the one year of living together and qualify for common law sponsorship. If I'm refused entry then that will hopefully then qualify me for Conjugal. If I stay in the Uk for the next couple of months then we are neither.
Alternatively, could your other half visit you in the UK? Short vacations are allowed within the year, so the time since you've left would be a vacation, you'd finish up the year to qualify and after that you can maintain your status even if you aren't continuously together (and you can explain distance based on refusal to extend your visa)
You can see details on p.27 of OP-2:
"How can someone in Canada sponsor a common-law partner from outside Canada when the definition says “is cohabiting”?
According to case law, the definition of common-law partner should be read as “an individual who is (ordinarily) cohabiting”. After the one year period of cohabitation has been established, the partners may live apart for periods of time without legally breaking the cohabitation. For example, a couple may have been separated due to armed conflict, illness of a family member, or for employment or education-related reasons, and therefore do not cohabit at present (see also 5.44 for information on persecution and penal control). Despite the break in cohabitation, a common- law relationship exists if the couple has cohabited continuously in a conjugal relationship in the past for at least one year and intend to do so again as soon as possible. There should be evidence demonstrating that both parties are continuing the relationship, such as visits, correspondence, and telephone calls.
This situation is similar to a marriage where the parties are temporarily separated or not cohabiting for a variety of reasons, but still considers themselves to be married and living in a conjugal relationship with their spouse with the intention of living together as soon as possible.
For common-law relationships (and marriage), the longer the period of separation without any cohabitation, the more difficult it is to establish that the common-law relationship (or marriage) still exists."
