Hi xaira!
The United Church of Canada was 'born' when four denominations got together - one of which was Methodist. In fact, you'd be hard pressed to find a Methodist church in Canada now, since they all became UCC.
Theologically, there are many similarities between the two, but since the merge also included Presbyterians and Congregationalists, the style and theology of the UCC took something from each. How much of the Methodist worship style and theology adopted is really more dependent on the congregation. The UCC covers a whole spectrum of worship styles and theological beliefs, and two UCC churches right down the street from each other might differ on many points.
The United Church of Canada is partners with other Methodist Churches in the world through the World Methodist Council, and in particular relationship with the Methodist Church in Haiti, the Colombian Methodist Church, the Ghana Calvary Methodist United Church, and more.
I hope this was of some help! If you're interested in learning more about The United Church of Canada, you can check out their website at
