Not sure if they'll hold it at the lounge, but there is a baggage storage place on the arrivals level. This might be easier than going through security to get the lounge (as you'll have to clear customs and exit the sterile area upon arrival from LGA).

I like Ottawa, but having spent countless nights downtown for work, I can tell you that there won't be much going on, especially on a Sunday.

As already mentioned, most of the stalls and stores in Byward Market will likely be closed. Though there are countless restaurants and bars that will likely be open - just don't expect much "street life". Same for most of the downtown area.

You MAY want to consider renting a car - I've seen some really cheap rates for Ottawa, and for the same price or a couple of dollars more than a cab, you'll have the freedom to explore different areas. And if you rent a car, then there is no issue with having to store your bag.

rent a car, drive to Gatineau park..

there are some very nice trails and lookouts..

you won't have time to visit them all, but you can pick one to get the taste of the park for next time :)

Ottawa is a fantastic City and 4-5 hours is enough to get a taste.

Arrival & Customs - 30 minutes

I suggest being dropped off at Chateau Laurier as it is a very central location and you may either head to see Parliament Hill, Walk the Rideau Canal or take a Stroll in the market.
(Time to Chateau Laurier - 20 minutes by Cab ~ $32 -35 CDN)

If you head to Parliament, take some time and walk around the building. Behind Parliament (near the library) is a great view of the river, Canadian Museum of Civilization etc.

From there you can walk back towards the Chateau Laurier and possibly around Majors Hill Park (behind Chateau Laurier). This will give you a nice view of the hill also.

If you decide to head into the market make sure you stop for a Beaver Tail (Beavertail) at the corner of George and Williams street before leaving. They taste great and are unique to Ottawa.

When you decide to head back to the airport make sure the cab driver takes you along the canal as it is a very nice drive.

I know this sounds like a lot but a couple hours should be enough to get a quick glance at the city… probably bringing you back for more in the near future.

Hope you enjoy your travels!

I echo Ian's views, but just so you know, a Beavertail isn't actually a beaver's tail, but a pastry. :)

All- thanks so much for your conscientious responses!

I've not flown the new in the new CO seats, but the concept is the same. AC has pods arranged in a herring bone fashion. There's also AVOD. They are quite comfortable.

And renting a car is not a bad option. It's cost effective, it's easy to get in and out of town, and there shouldn't be any problem parking at that time of day on a Sunday.

Opps, typo... thanks!

Very good suggestion. You could check your bag with the hotel bell desk for the price of a tip.

Depending on your interests (and the weather), you might also consider these two museums:

if not all, most museums will be closed Sundays by 5pm :td:

GUYS, C'mon!!!!!!

My advice, to get yourself pepped up, if in the Market area, check Barefax ...if you take a rental, don't miss Gatineau's Pigale... :D

EAT: Empire Grill
DRINK: Heart & Crown

go swimming in the waterfall/pool at the airport :D

Um, go shopping; some nice stores in Rideau Centre, have lunch in the market, or down elgin, and then hop back on the bus to the airport. Thanks to the transitway you can get to downtown very easy with one bus

You can visit your embassy along Sussex; one huuuuuuugggggggggeeeeeeeeee building. I mean from the outside. Walk up the street to the Parliament building and laugh at us for not having a stable government :D But no its a very nice picture spot. I do appologize for one thing though. Do not walk along King Edward below Rideau (/ Wellington), it's pretty sketchy (IMO).

Oh yeah, by the embassy is the rideau canal a little further up the road. There are some locks there, if you time it correctly (or lucky enough) you may see a boat passing through them

EDIT: Sorry I saw that you will be there from 5-10pm...alas you may not find much to do on a Sunday...i hope you do find something to do. It is a sleepy town, but it does have its moments

oh god you said pigale!!! :D I think there is a good one in the market - i would add something to that statement but it would be mean :)

Oh, and you don't need a passport to enter Quebec (and hopefully you never will) lol :D
