I feel badly for remote communities that were looking forward to these services, but Starlink is a security threat directly connected to a hostile nation that has been making overt threats to Canada. Moreover, we have already seen Musk will direct the company to turn off access to people he doesn't like. There would have been nothing stopping Musk (his lackeys) from eavesdropping on communications and then cutting it off when he felt like it.
The only real way is to invest in other providers, preferably Canadian, preferably public, but most fundamentally anyone that's not MAGA.
I used Studio Tax for a few years and found it to be adequate. Last year I tried GenuTax and instead and I didn't like it as much. Instead of presenting you with the forms and you fulling them (which StudioTax does) GenuTax asks you a million yes/no questions one at a time. If you select "yes", then it shows you appropriate, corresponding form to fill out.
I guess the good thing about this method is you are presented all the possibilities, the bad thing is you have to yes/no everything, including a million things that probably don't apply to you.
Also, its not always immediately clear what form a yes/no will lead to, meaning if you select something wrong, you have to back track to correct it. (The questionnaire is linear, you can't just jump back and forth.) if you have a very basic return, that's probably fine. But I had some small self-employed income and international tuition, and going back and forth trying to yes/no my way to the correct forms frustrated me enough to switch back to StudioTax and start again.
