Justin and Hailey Bieber are serving serious couple goals -- spotted locking lips at a dreamy lakeside getaway, and honestly, the PDA is off the charts!

Check out the pics Justin dropped Sunday -- the two lovebirds were in his native Canada, heating up the chilly Lake Louise vibes with some seriously steamy kisses.

The two were clearly head-over-heels, soaking up the breathtaking scenery and each other, totally lost in their own world.

Their getaway was pure Canadian wilderness -- lakes, wildlife, and all -- with Hailey sharing a sweet canoe pic from the trip on her platform.

Looks like these two are totally back on track -- earlier this year, Hailey went MIA with her wedding ring and Biebs’ fans freaked out thinking things were off.
