Canada taking St. Pierre and Miquelon in 2016 would be easy; holding it from a determined French counterattack would be less so, especially with Canada's current land based airforce. The CF18s are pretty old and there are only 79 in operational use, and even then probably only a fraction of these can be deployed to airbases in striking range on the east coast. Given that the DeGaulle can theoretically carry 35 Rafalee fighters (normally it is 18 Rafales and 8 Super Étendards) I am not entirely sure that even with the bulk of the RCAF fighters deployed to the east coast air dominance over the region would be assured. Also, considering we are down to a single ancient air-defense destroyer (HMCS Athabaskan) and 12 less capable Halifax class frigates along with a collection of patrol ships and 4 90s vintage British hunter-killer subs with less than stellar service records (they like to catch fire) I am not sure the Canadian navy would be looking for any sort of confrontation with the French task force, even if the CF-18s establish air superiority. Canada wouldn't be as grossly outclassed as Argentina was against the RN (our military may be relatively paltry by Western standards but it is still light-years better trained and equipped then a third-world conscript force; which is what the Junta backed invasion force was at the time), but when you break down the specifics, the numbers are far less one-sided in favor for the Canadians then it might seem at first glance; yes they have numbers and the luxury of operating out of their home-bases, but the risk of the French fleet inflicting some pretty humiliating losses to Canadian air and sea assets, in Canadian waters at that, is a real possibility.
Totally ASB from a political standpoint, but interesting to talk about. Makes me think of something like an AH version of the "
Turbot War" that would have pitted Canada against Spain in 1995 (back when Canada's pretty much identical to 2015 air and sea asset were 20 years younger and still seen as close to 1st rate platforms).
