Welcome.
The lighting package refers to the headlights, not the tails. In the 2018s, the lighting package (or at least the upgraded headlights) would be the all LED headlights found on the upper GTI trims and the Golf R. Seeing you're in Canada, I don't know if the lighting package is an option for the 1.8T Golf up there.
As for tails, all NAR Golfs come with LED taillights now. The taillights are the same as the low-line tails found in RoW, which are not dynamic. In order to get the dynamic tails, you'll have to buy the tail light parts, maybe do a bit of wiring (or get some sort of harness), and do a bit of coding.
This thread is for the MK7 (2015 - 2017) to MK7.5 taillight retrofit, but you can find the appropriate part numbers for the dynamic taillights:
