Where to begin my Pokemon collecting card journey? Hello Folks,

I have decided to start collecting pokemon cards. I used to collect it like 20 years ago when it was simple and only one generation of pokemon. Like a idiot I sold it. Recently my fiance gifted me nintendo switch and pokemon go. The more I played it, the more I missed the world of pokemon. 

So here I'm starting my journey. I would really appreciate if I could get some tips to what pack to buy, where to buy (Live in Canada) and anything to help me. It is overwhelming the amount of cards and pack there is. I do not know where to start. 

At the moment I want to just collect everything. I dont want card specifically for TCG. Maybe down the road I will.
