Are Canadian LG plasma TVs different than American models?

I have been researching LG plama TVs and noticed that those advertised on American websites typically carry PG (ie. 50PG30) in their model number; whereas Canadian retaillers advertise PQ (ie. 50PQ30) in their model numbers. Are they the same, the sets seem to have very minor differences, but the websites are often incomplete. I ask this because I am researching new TVs and want to know what quality of info I am finding on the internet.

they’re compatible
