Foreflight & ADSB Receiver For GA Flying In Canada

Assuming I'm overthinking this but I wanted to see if people had recommendations or if I'm missing anything.

I'm applying for my PPL so I'll be starting hobby flying soon and wanted to increase my safety when I do so.

From what I can find by searching online and in this sub, I see people recommend Foreflight a lot, which seems to be good for gps/weather info and some other stuff? I would need to get an ipad to use it but that's whatever.

For an ADSB receiver then (to help with traffic), should I get a Sentry since its directly compatible with foreflight? Or do people recommend some other receiver (or even alternative to foreflight)?

Thanks in advance
