canadalover4987, I am in a similar situation to yours. We met first online in 2011 and in person in 2013 when i traveled to Philippines as part of an Asia vacation. We applied and were refused TRVs 4 times in 2014 and I traveled to the Philippines twice more during that time frame. For each of the 4 TRV trys there was some change in the circumstance or something more to help our case, but no luck. After the first two refusals, we started preparing for a conjugal PR filing. We could not file the PR until after July 2014 because I was still married in Canada and had to be separated for a year in order to qualify as a sponsor.
Against the advice of many on this board, we filed our conjugal PR application in August 2014. By then I had visited three times and we had spent about six weeks together in person. We also started building a house together in the Philippines so we would have a safe place when we are there together. Despite all of this, I know that receiving approval is still a long shot. It has been 6 months since the PR file was transferred to Manila.
I took my 4th trip to the Philippines in a year in October 2014 and while there my partner received confirmation that her file was at Manila VO. As soon as I returned to Canada, we applied for a TRV again (5th try) and finally this time we were approved. My partner has been in Canada for 5 months now. If we applied for an extension for her stay here, we might very well be able to become common law partners before she has to leave the country. Nevertheless, we are going to the Philippines in April - my partner, her return ticket and me for a two week vacation. As soon as we arrive and her passport is stamped, we will apply for another TRV and are hopeful that she will get another TRV to return to Canada with me.
Your best option to be with your partner is to apply for a TRV. It is a relatively simple and cheap process and can be done 100% on-line. Make sure she includes proof of her assets including cash in the bank. You will also have to show proof that you can support her while she is in Canada (i.e copies of bank statements). At this point I might suggest you not make a big deal about your conjugal relationship - don't use that word until you have applied for the PR. You will have a better chance than we did because my partner did not have a good job or any assets when we first applied (she lost both in the Tacloban typhoon).
If you are lucky and get a TRV, you should try to become common law partners (or get married) before making the application.
In our case, the PR is not as important as us being together. Yes it is more costly. Your partner can't work; you have to buy your own health insurance; you may have expensive travel that you would not otherwise choose to take.
Good luck! I will update the board regarding our upcoming TRV application. In the meantime, I am not expecting any progress on our conjugal PR application for several more months. If my partner gets another TRV I don't mind if we hear nothing on the PR for another 6 months.
