Angular2 routeLink not working when querystring value is a 1

Question

I have this router link:

<a [routerLink]="['RepairReturnListing', {country: someVal}]">Test</a>

In my component I define someVal like this:

export class RepairReturnCountByCountry {
   ...
   someVal: number = 1;
   ...
}

When the value is 1 I get this URL:

http://localhost:54675/repairReturnListing?country

Notice, no equals sign and no value.
I display the value in a div and it works as expected.

<div>{{someVal}}</div>

If I change it to anything other than one (even -1) I get a valid URL:

http://localhost:54675/repairReturnListing?country=0
http://localhost:54675/repairReturnListing?country=2
http://localhost:54675/repairReturnListing?country=777
http://localhost:54675/repairReturnListing?country=-1

If I remove someVal from the component I get:

http://localhost:54675/repairReturnListing?country=null

I change someVal to a string but I get the same results:

 someVal: string = '1';

Here is my routeConfig:

 @RouteConfig([
        { path: '/repairReturnListing', name: 'RepairReturnListing', component: ListingComponent, useAsDefault: false }
])
