Traveling to Canada...what to wear?

I am traveling to Vancouver next week, and I saw that the temps will be in the high 60s during the day. Since I am from the south US, I am so not used to this type of weather in the summer. I am going to bring long sleeve shirts and such, but what type of shoes should I bring? Is it too cold to wear open toe shoes?

pants

Bring a pair of flip flops, sneakers, and if you want to dress up at all whatever you want extra - the weather should be nice enough for jeans/shorts and a tshirt - treat it like how you'd dress in early spring

I think you should wear warm clothes because since its near the top of the world it'll be kinda cold but pack a cool outfit just in case

a jacket.
i went to montana and canada is right above and i went this summer and it was still cold.
lowest was 49 degrees. high was 80.
it was nice there.

Dress for winter in the deep south, but bring some summer things as well. The weather can vary there from one hour to the next!
