Here's what chat gpt had to say, usually it does pretty ok, not this time, as i feel you probably think yours is older then mid 1990's lol
Congrats on the inheritance! Short answer: there isn’t a public, factory serial-number table for Lakefield-branded Mark II rifles, so you can only bracket the year. Based on known, documented examples:
A Lakefield Mark II with SN ~298,357 has been cited as circa 1993. 
Another owner reported SN 274,743 as a Lakefield-marked import (clearly pre-Savage branding), again pointing to the early–mid 1990s. 
Savage bought Lakefield in 1995; pre-’95 rifles typically carry “Lakefield Arms” markings. 
Collectors on Canadian Gun Nutz also note there’s no official serial/date chart and suggest contacting the Lakefield plant directly rather than U.S. customer service. 
Your serial 247,171 sits below those early-’90s examples, so a realistic estimate is ~1991–1992 (±1–2 years).
Ways to tighten the estimate
Markings & features: If it’s roll-marked “Lakefield Arms Co. Ltd.” with no Savage branding and uses the earlier extractor style, that supports pre-1995 manufacture. (This aligns with the collector guidance above.) 
Call Savage (Lakefield, ON) directly: Community reports say the local Lakefield number is more helpful for pre-1995 guns than the U.S. 1-800 line. Be ready with your serial and clear photos of the receiver and barrel stamps. 
If you want, drop a couple of clear photos of the receiver markings, barrel roll-marks, and extractor/bolt face, and I’ll help you narrow it further.
