Hole in Tire - what to do?

If it has a hole, it can be repaired with a patch as long as the hole isn't on the side wall, or close to it.

Take it to a Tire Shop & get it fixed properly from the inside. This is a good one - http://simplytire.com/

Kaltire does free tire patch if they see you as potential customer.

Take it to a tire shop for a patch. If there is indeed a puncture.

Just tell them it's leaking air, and they'll fix it.

Use a plug kit from CT if you don't mind doing DIY. Otherwise take to tire shop to fix for you if it isn't in the sidewall.
If you can't find the leak, spray the tire with soapy water to find it. You may need to rotate it to find it. If you still can't find it, be sure to spray the tire valve, as sometimes that can leak. Rarely the inside of the metal wheel can have a pinhole leak.
If you still can't find it, fill a tub with water, and submerge parts of the tire in it until you see bubbles. It helps to over pressure the tire to 50psi to see more bubbles, but if it takes you that long to get to 34psi, you probably have a big leak or a broken pump.
Anyhow, find the leak, mark it and fix DIY or take to tire shop.

Its also common on older rims to develop a small leak where the rim and rubber connect to each other from rust or corrosion. The shop can remove the tire, grind down the rust and put it back on. Take it into a good shop and they should be able to fix it up and send you on your way, it's around 30$ give or take depending on the shop I think.

Or do I need tire? If so, do I have to replace all 4 or just the one? This is the second winter season of use. The car only has about 18,000 km on it.

If your car only has 18,000 km on it, take it to the dealer. It could be a warranty issue.

Tires won't be covered under warranty unless he bought extra tire hazard warranty or insurance. But worth a shot, my nissan came with 60k kms bumper to bumper and free hazard warranty. Didn't use it but, my MB had a flat at 5000 kms and they brushed me off and ask me to pay $400+$100 for installation. I laughed and left. Spent $5 at CT for plug and returned the car a year later.

Just want you to be crystal clear on this...Everyone is telling you to take it to a "Tire" Shop...NOT Canadian Tire! Thought you should be aware.

Because I don't want to see another thread open with title.."Took it to Canadian Tire and they blew my engine into pieces"...

Okay, OP don't take this the wrong way, but if you are starting this thread, asking these questions, I feel a DIY plug kit is not the best option for you.

Take it a tire shop and have it looked at. If it can hold pressure for 16 hours, then pump it up to 35psi and go straight there. Call them ahead so they know you are coming. As said, as long as not near the sidewall, it can likely be fixed no problem. I just had one done, for $25. Usually I buy the road hazard warranty, but unfortunately I bought these Hankook tires though my Goodyear mechanic, and they can only offer it on Goodyear tires. Odd policy, but whatever.
