It was due to a cracked windshield and pressurization issues. Following from Transport Canada daily occurrence reports.
AFR085, a Boeing 777-200 operated by Air France, was en route IFR from San Francisco (KSFO) to Paris-Charles de Gaulle (LFPG). At 0630Z in the vicinity of 63N/80W, the crew declared an emergency due to a pressurization problem resulting from a crack in the windscreen. The aircraft descended to an altitude of 10,000 feet in order to stabilize the situation and requested to divert to Montréal/Trudeau (CYUL). Shortly thereafter the crew cancelled the emergency but continued to Montréal/Trudeau. The aircraft landed without incident at 0929Z. No impact on ATC operations.
No pressurisation issues, although one could say they descended to FL100 so that one did not develop! Another benefit of flying to Montreal at low level would be vastly increased fuel consumption so they could land within their max landing weight.
