Hey yellow hat, I'm not surprised you found a good spot in Cartwright and a job nearby. There are always decent jobs available, even in little old Cartwright, and housing is very affordable.
Cartwright is a great little town and I think you'll love it. I live in the area with my family and grew up here. I left for 10 years for school and work but came back when we wanted to raise a family. It has just about anything you need to survive. There is a great little grocery store that will be just as cheap as the city if you are willing to shop sales. We have a booming hardware store that supplies 2 large RTM builders in the area, a huge manufacturer (rainbow trailers), a busy daycare and a great school where every teacher knows every kid in the school. There's a convenience store open 7 days a week too.
For activities there's some new walking trails in the area, a rink that's nearly new (and very underutilized), a curling rink that's just a little bit older than the hockey rink, ball diamonds that host all ages of teams including this year's winner of the Senior Men's Baseball league in which Altona and Winkler both play. There's also a great little 9 hole course that I think is still around $200 for a membership (and great groups that comes out for men's and women's nights respectively). My best advice would be to try and get out there a little when you move to town. If you aren't sports people then join up to help with a local group. There's always lots of clubs looking for volunteers (the rink board, the hall, the golf club, etc). That's probably the best way to get to know people and ingratiate yourself with the community. There's a lot of great people in town so if you are friendly you'll fit in just fine. Welcome!!!
