Starting Monday, the Zune Music Marketplace and Zune Music Pass is expanding north, giving Windows Phone owners in Canada access to music. A Zune Pass will cost C$9.99 per month (or C$99.90 a year). Besides a Windows Phone, subscribers can also listen on a Xbox 360, Windows PC, Zune device, and Zune.net.

That?s not the only big Zune news today. Starting Monday, Zune Music Pass subscribers in the US and Canada can also now stream music videos through the Zune PC software (and soon the Xbox 360).

Budget-minded music buffs are also in luck. On Monday, Microsoft starts selling a new, less-expensive Zune Music Pass. The new plan costs $9.99 a month (about $5 cheaper than the current plan) but gives you unlimited, on-demand access to the same catalog of music and (now) music videos. It also includes unlimited streaming access on a Xbox 360 and Zune.net.

However, under the new plan, you no longer get 10 free MP3s to keep each month. Current subscribers can stay on the $14.99 plan with 10 free downloads, if they choose.

Subscribers to the $9.99 plan can synch downloaded songs with up to four devices (1 PC + any combination of PC, Zune HD, or Windows Phone).
