Because the wind comes off the sea, laden with moisture, and is forced upward by the mountains causing the air to cool and that causes rain. Because of the rotation of the earth, winds in Vancouver are from the sea to the land. At other latitudes, the predominant wind is from the land to the sea (eg parts of Chile). The trip over the Andes strips the air of water on the eastern side (ending up in the Amazon), so on the west side there is no moisture and the coast is dry.

Living in the Pacific Northwest like I do, you have to expect this kind of weather. The reason it rains so much is that storms come in from the Pacific and since the mountains are just to your East, it squeezes the moisture out of them, depending on how potent the system is, depends on how much rain you get, it also depends on how close to the low pressure system you are as well.
