I see so many issues with your understanding of the scenario at hand. While I do not wish to divulge details of my situation I will state that:
a) It is not always 'easier' for a spouse in Canada to visit their partner instead. For example, one spouse may have more rigorous job commitments and not be able to take adequate time off (please note that not everyone can work remotely), the spouse in Canada may have to take care of an ailing parent or their children and may not be able to leave them behind or the spouse in Canada may even have some underlying health conditions or comorbidities that might place them at a higher risk of traveling during the pandemic. These are just some examples off the top of my head, again we do not know anyone's personal situation well enough to know what is easier and doable for them and what is not.
b) There are some countries that have already kick-started their family reunification processes and are specifically issuing visas for this purpose because again, family reunification is IMPORTANT. From signing petitions and spreading our story in the media to sliding in a Minister's DMs - there is nothing wrong with taking an initiative or making an effort to streamline things.
Yes, a TRV has higher chances of getting rejected when a family sponsorship application is underway but I personally know of cases where it has been granted (even during COVID-19, yes that happened!) so I would personally not discourage anyone from taking a shot and filling a TRV application wisely based on the experiences of those who have got one. If I even have a 1% chance of being with my spouse sooner rather than much much later, you best believe I will take that shot, as long as it complies with the law.
Good for you then ! if you can capitalize on the 1% chance you spoke of it'll be wonderful ! By no means you'll see your spouse in no time ,But with how slow things are going though i don't know if a TRV is going to be processed as fast as normal .
TRV's are also processed by the currently understaffed institution , TRV's require documents to be verified by your local Canadian high commission , TRV's require medical tests , I don't know where you live right now but I am pretty sure where ever it is one of the above procedures will bottleneck at one point or another due to the ongoing lock down .
After all it's your call to make , and your time to spend my dear . I wish everyone luck and pray that there gets to be a pick up in the slack caused by the lockdown restrictions .
