Foreign designs for new Navy ships?

The government has accepted using, for cost reasons, a Dutch design for the Canadian Coast Guard's new Mid-Shore Patrol Vessels. Meanwhile procurement of two new types of Navy vessels, the Joint Support Ship and Arctic/Offshore Patrol Ship, languishes on and on since Canadian shipyards are unable to design and build them as specified at a price the government is willing/able to pay.

Surely foreign designs, to be built in Canada, might also be selected in these cases in order to reduce costs. After all we've already talked with the Dutch who are planning something very like the JSS:

And a Norwegian type was reported earlier as being a possible model for the A/OPS, but then it was decided that "...the vessels will not be based on the Norwegian Svalbard class as previously reported in the media...". More here on the Svalbord:

Other foreign designs might also be looked at, e.g. the Danish Thetis class.
