Good on you for wanting to keep riding despite the nastiness that is a Vancouver winter.

There is a lot of gear choices out there and my girl is a fan of Showers Pass jackets and pants out of Oregon as she says these provide the best rain protection of anything she has used.

And she sees a lot of rain.

Add to that a helmet cover, waterproof shoes or covers, and fenders for your bike and you should be pretty well set.

The fenders protect the bike and especially it's drive from becoming cruddy, protect you, and will also preserve the headset as getting water in that will ruin it in short order.

If you are looking for a road bike make sure it will accommodate fenders... a cross bike or touring bike can be a very good choice if your riding will be more utilitarian.
