Canadian dollars, and he probably would need to upgrade the PSU. 500 watts is borderline especially if he has a cheap PSU.
IT WOULD DEFINETILY NOT BE A BORDERLINE
It would be borderline at best xApple77, especially without knowing the quality of the PSU the OP has.
The GTX 950 is the best you can do at $200 CDN, as has been said - although they do tend to be factoring in $10-$20 rebates to meet your $200 requirement.
It depends how firm your budget it - if you can stretch the extra $20 initially, the 950 is the way to go.
An alternative though: R7 370's, which are decent budget cards - the GTX 950 is the slightly better performer by around 8% better frame rates though, but the 370 can be found for $180 without having to deal with rebates.

Otherwise, anything else/better is going to be substantially over budget, and in some cases may also need you to upgrade your PSU.
