Exhaust vent distnace to window

Anyone know if there is any regulation/by-laws in Markham/Ontario that dictates the distances between an exhaust vent and a window?
My dad used to be a building inspector in California and said that they had a regulation that there was a minimum distance of 4' between a window and an exhaust vent.

I assume you are referring to a hot water tank or furnace.

The answer is yes.

I believe that it needs to be at least 1 ft off the ground level.
No closer than 3 ft to any natural gas regulator and I believe at least 1 ft from any window that is operational (can open).

Someone had also mentioned in the last that if your furnace is larger (more than 100k btu) the distances change.

Sorry, I was referring to the kitchen exhaust.
I forgot to mention because everyone should just automatically know what I was thinking.
Sorry about that.

I knew there were rules for venting furnaces and hot water heaters, but I've never heard of similar rules for general exhaust vents.

I mean common sense should dictate not to have it within inches of an openable window...

The thing they have in California is 4 feet from an openable window.
